General Description
The TC1054, TC1055 and TC1186 are high accuracy (typically 0.5%) CMOS upgrades for older (bipolar) low dropout regulators. Designed specifically for battery-operated systems, the devices' CMOS construction eliminates wasted ground current, significantly extending battery life. Total supply current is typically 50A at full load (20 to 60 times lower than in bipolar regulators). The devices' key features include ultra low noise operation, very low dropout voltage - typically 85mV (TC1054); 180mV (TC1055); and 270mV (TC1186) 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). ERROR can be used as a low battery warning or as a processor RESET signal (with the addition of an external RC network). Supply current is reduced to 0.5A (max) and both V OUT and ERROR are disabled when the shutdown input is low. The devices incorporate both over-temperature and over-current protection. The TC1054, TC1055 and TC1186 are stable with an output capacitor of only 1F and have a maximum output current of 50mA, 100mA and 150mA, respectively. For higher output current regulators, please see the TC1173 (IOUT = 300mA) data sheet.

The maximum allowable power dissipation is a function of ambient temperature, the maximum allowable junction temperature and the thermal resistance from junction-to-air (i.e., TA, TJ, JA). Exceeding the maximum allowable power dissipation causes the device to initiate thermal shutdown. Please see Section 4.0 Thermal Considerations for more details. Hysteresis voltage is referenced by VR. The minimum VIN has to justify the conditions: VIN VR + VDROPOUT and VIN 2.7V for IL = 0.1mA to IOUTMAX .

3.0 DETAILED DESCRIPTION
3.1 ERROR Open Drain Output
The TC1054, TC1055 and TC1186 are precision fixed output voltage regulators. (If an adjustable version is desired, please see the TC1070/TC1071/TC1187 data sheet.) Unlike bipolar regulators, the TC1054, TC1055 and TC1186 supply current does not increase with load current. In addition, VOUT remains stable and within regulation over the entire 0mA to IOUTMAX operating load current range, (an important consideration in RTC and CMOS RAM battery back-up applications). Figure 3-1 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 0.05A (typical), VOUT falls to zero volts, and ERROR is opencircuited. 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 (typ.) for a 5.0V regulator and 2.85V (typ.) for a 3.0V regulator). ERROR output operation is shown in Figure 3-2. Note that ERROR is active when VOUT falls to VTH, and inactive when VOUT rises above VTH by V HYS. As shown in Figure 3-1, 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 msec 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).

3.2
Output Capacitor
A 1F (min) capacitor from VOUT to ground is recommended. The output capacitor should have an effective series resistance greater than 0.1 and less than 5.0, and a resonant frequency above 1MHz. A 1F capacitor should be connected from V IN to GND if there is more than 10 inches of wire between the regulator and the AC filter capacitor, or if a battery is used as the power source. Aluminum electrolytic or tantalum capacitor types 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.

4.1
THERMAL CONSIDERATIONS
Thermal Shutdown
Equation 4-1 can be used in conjunction with Equation 4-2 to ensure regulator thermal operation is within limits. For example: Given: VINMAX = 3.0V 5% VOUTMIN = 2.7V - 2.5% ILOADMAX = 40mA TJMAX TAMAX = 125C = 55C
Integrated thermal protection circuitry shuts the regulator off when die temperature exceeds 160C. The regulator remains off until the die temperature drops to approximately 150C.
4.2
Power Dissipation
The amount of power the regulator dissipates is primarily a function of input and output voltage, and output current. The following equation is used to calculate worst case actual power dissipation:
Find: 1. Actual power dissipation 2. Maximum allowable dissipation Actual power dissipation: PD (VINMAX - VOUTMIN)ILOADMAX = [(3.0 x 1.05) - (2.7 x .975)]40 x 10-3 = 20.7mW Maximum allowable power dissipation: PDMAX = (TJMAX - TAMAX) JA = (125 - 55) 220 = 318mW In this example, the TC1054 dissipates a maximum of 20.7mW; below the allowable limit of 318mW. In a similar manner, Equation 4-1 and Equation 4-2 can be used to calculate maximum current and/or input voltage limits.
EQUATION 4-1:
PD (VINMAX - VOUTMIN)ILOADMAX Where: PD VINMAX VOUTMIN ILOADMAX = Worst case actual power dissipation = Maximum voltage on VIN = Minimum regulator output voltage = Maximum output (load) current
The maximum allowable power dissipation (Equation 4-2) is a function of the maximum ambient temperature (TAMAX), the maximum allowable die temperature (TJMAX) and the thermal resistance from junction-to-air (JA). The 5-Pin SOT-23A package has a JA of approximately 220C/Watt.
EQUATION 4-2:
PDMAX= (TJMAX - TAMAX) JA Where all terms are previously defined.
4.3
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.
