General Description
The TC2054, TC2055 and TC2186 are high accuracy (typically 0.4%) CMOS upgrades for older (bipolar) low dropout regulators. Designed specifically for battery-operated systems, the devices' total supply current is typically 55 A at full load (20 to 60 times lower than in bipolar regulators). The devices' key features include low noise operation, low dropout voltage - typically 45 mV (TC2054); 90 mV (TC2055); and 140 mV (TC2186) at full load - and fast response to step changes in load. An error output (ERROR) is asserted when the devices are out-of-regulation (due to a low input voltage or excessive output current). Supply current is reduced to 0.5 A (maximum) and both VOUT and ERROR are disabled when the shutdown input is low. The devices also incorporate overcurrent and overtemperature protection. The TC2054, TC2055 and TC2186 are stable with a low esr ceramic output capacitor of 1 F and have a maximum output current of 50 mA, 100 mA and 150 mA, respectively. This LDO Family also features a fast response time (60 s typically) when released from shutdown.

Out-of-Regulation Flag (ERROR)
Connect the unregulated input supply to the VIN pin. If there is a large distance between the input supply and the LDO regulator, some input capacitance is necessary for proper operation. A 1 F capacitor, connected from VIN to ground, is recommended for most applications.
The open-drain ERROR flag provides indication that the regulator output voltage is not in regulation. The ERROR pin will be low when the output is typically below 5% of its specified value.

4.0 DETAILED DESCRIPTION
VOUT VTH HYSTERESIS (VHYS)
The TC2054, TC2055 and TC2186 are precision fixed output voltage regulators. (If an adjustable version is desired, refer to the TC1070/TC1071/TC1187 data sheet (DS21353). Unlike bipolar regulators, the TC2054, TC2055 and TC2186 supply current does not increase with load current. In addition, VOUT remains stable and within regulation over the entire 0 mA to maximum output current operating load range. Figure 4-1 shows a typical application circuit. The regulator is enabled any time the shutdown input (SHDN) is at or above VIH, and shutdown (disabled) when SHDN is at or below VIL. SHDN may be controlled by a CMOS logic gate, or I/O port of a microcontroller. If the SHDN input is not required, it should be connected directly to the input supply. While in shutdown, supply current decreases to 0.05 A (typical), VOUT falls to zero volts, and ERROR is open-circuited.

A 1 F (minimum) capacitor from VOUT to ground is required. The output capacitor should have an effective series resistance of 0.01. to 5 for VOUT = 2.5V, and 0.05. to 5 for VOUT < 2.5V. Ceramic, tantalum and aluminum electrolytic capacitors can be used. (Since many aluminum electrolytic capacitors freeze at approximately -30C, solid tantalums are recommended for applications operating below -25C). When operating from sources other than batteries, supply-noise rejection and transient response can be improved by increasing the value of the input and output capacitors and employing passive filtering techniques.

ERROR Open-Drain Output
ERROR is driven low whenever VOUT falls out of regulation by more than -5% (typical). This condition may be caused by low input voltage, output current limiting or thermal limiting. The ERROR threshold is 5% below rated VOUT regardless of the programmed output voltage value (e.g. ERROR = VOL at 4.75V (typical) for a 5.0V regulator and 2.85V (typical) for a 3.0V regulator). ERROR output operation is shown in Figure 4-2. Note that ERROR is active when VOUT falls to VTH, and inactive when VOUT rises above VTH by VHYS. As shown in Figure 4-1, ERROR can be used as a battery low flag or as a processor RESET signal (with the addition of timing capacitor C2). R1 x C2 should be chosen to maintain ERROR below VIH of the processor RESET input for at least 200 ms to allow time for the system to stabilize. Pull-up resistor R1 can be tied to VOUT, VIN or any other voltage less than (VIN + 0.3V). The ERROR pin sink current is self-limiting to approximately 18 mA.
A 1 F capacitor should be connected from VIN to GND if there is more than 10 inches of wire between the regulator and this AC filter capacitor, or if a battery is used as the power source. Aluminum electrolytic or tantalum capacitors can be used (since many aluminum electrolytic capacitors freeze at approximately -30C, solid tantalum are recommended for applications operating below -25C). When operating from sources other than batteries, supply-noise rejection and transient response can be improved by increasing the value of the input and output capacitors and employing passive filtering techniques.

THERMAL CONSIDERATIONS
Thermal Shutdown
Equation 5-1 can be used in conjunction with Equation 5-2 to ensure regulator thermal operation is within limits. For example: Given: VINMAX VOUTMIN TAMAX Find: 1. Actual power dissipation 2. Maximum allowable dissipation Actual power dissipation: P D = ( V INMAX - V OUTMIN )I LOADMAX = [ ( 3.0 x 1.1 ) - ( 2.7 x 0.975 ) ]40 x 10
-3
Integrated thermal protection circuitry shuts the regulator off when the die temperature exceeds approximately 160C. The regulator remains off until the die temperature cools to approximatley 150C.
= 3.0V +10% = 2.7V - 2.5% = +55C
ILOADMAX = 40 mA
5.2
Power Dissipation
The amount of power the regulator dissipates is primarily a function of input and output voltage, and output current. Equation 5-1 is used to calculate worst case power dissipation:
EQUATION 5-1:
P D ( V INMAX - V OUTMIN )I LOADMAX Where: PD VINMAX VOUTMIN = Worst-case actual power dissipation = Maximum voltage on VIN = Minimum regulator output voltage
= 26.7mW Maximum allowable power dissipation: T JMAX - T AMAX P DMAX = ------------------------------------- JA = 125 - 55 -------------------220 = 318mW In this example, the TC2054 dissipates a maximum of only 26.7 mW; far below the allowable limit of 318 mW. In a similar manner, Equation 5-1 and Equation 5-2 can be used to calculate maximum current and/or input voltage limits.
ILOADMAX = Maximum output (load) current The maximum allowable power dissipation (Equation 5-2) is a function of the maximum ambient temperature (TAMAX), the maximum allowable die temperature (125 C) and the thermal resistance from junction-to-air (JA). The 5-Pin SOT-23A package has a JA of approximately 220C/Watt when mounted on a typical two layer FR4 dielectric copper clad PC board.
EQUATION 5-2:
T JMAX - T AMAX P DMAX = ------------------------------------- JA Where all terms are previously defined.
5.3
Layout Considerations
The primary path of heat conduction out of the package is via the package leads. Therefore, layouts having a ground plane, wide traces at the pads, and wide power supply bus lines combine to lower JA and, therefore, increase the maximum allowable power dissipation limit.

Note the following details of the code protection feature on Microchip devices: * * Microchip products meet the specification contained in their particular Microchip Data Sheet. Microchip believes that its family of products is one of the most secure families of its kind on the market today, when used in the intended manner and under normal conditions. There are dishonest and possibly illegal methods used to breach the code protection feature. All of these methods, to our knowledge, require using the Microchip products in a manner outside the operating specifications contained in Microchip's Data Sheets. Most likely, the person doing so is engaged in theft of intellectual property. Microchip is willing to work with the customer who is concerned about the integrity of their code. Neither Microchip nor any other semiconductor manufacturer can guarantee the security of their code. Code protection does not mean that we are guaranteeing the product as "unbreakable."
