General Description
The TC2014, TC2015 and TC2185 are high-accuracy (typically 0.4%) CMOS upgrades for bipolar Low Drop-out Regulators (LDOs), such as the LP2980. Total supply current is typically 55 A; 20 to 60 times lower than in bipolar regulators. The key features of the device include low noise operation (plus bypass reference), low dropout voltage - typically 45 mV for the TC2014, 90 mV for the TC2015, and 140 mV for the TC2185, at full load - and fast response to step changes in load. Supply current is reduced to 0.5 A (max) and VOUT falls to zero when the shutdown input is low. These devices also incorporate overcurrent and overtemperature protection. The TC2014, TC2015 and TC2185 are stable with an output capacitor of 1 F and have maximum output currents of 50 mA, 100 mA and 150 mA, respectively. For higher-output current versions, see the TC1107 (DS21356), TC1108 (DS21357) and TC1173 (DS21362) (IOUT = 300 mA) data sheets.

3.0 PIN DESCRIPTIONS
3.3 Shutdown Control Input (SHDN)
The descriptions of the pins are described in Table 3-1. The regulator is fully enabled when a logic-high is applied to SHDN. The regulator enters shutdown when a logic-low is applied to this input. During shutdown, the output voltage falls to zero and the supply current is reduced to 0.5 A (max).

3.4
Reference Bypass Input (Bypass)
3.1
Unregulated Supply Input (VIN)
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.
Connecting a low-value ceramic capacitor to Bypass will further reduce output voltage noise and improve the Power Supply Ripple Rejection (PSRR) performance of the LDO. Typical values from 470 pF to 0.01 F are suggested. While smaller and larger values can be used, these affect the speed at which the LDO output voltage rises when input power is applied. The larger the bypass capacitor, the slower the output voltage will rise.

Regulated Voltage Output (VOUT)

Ground Terminal (GND)
Connect the output load to VOUT of the LDO. Also connect one side of the LDO output de-coupling capacitor as close as possible to the VOUT pin.
Connect the unregulated input supply ground return to GND. Also connect one side of the 1 F typical input decoupling capacitor close to this pin and one side of the output capacitor COUT to this pin.

4.0 DETAILED DESCRIPTION
4.1 Bypass Input
The TC2014, TC2015 and TC2185 are precision fixedoutput voltage regulators (if an adjustable version is needed, see the TC1070, TC1071 and TC1187 (DS21353) data sheet). Unlike bipolar regulators, the TC2014, TC2015 and TC2185 supply current does not increase with load current. In addition, the LDO's output voltage is stable using 1 F of ceramic or tantalum capacitance over the entire specified input voltage range and output current range. Figure 4-1 shows a typical application circuit. The regulator is enabled anytime the shutdown input (SHDN) is at or above VIH, and disabled (shutdown) 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, the supply current decreases to 0.05 A (typical) and VOUT falls to zero volts. A 0.01 F ceramic capacitor, connected from the Bypass input to ground, reduces noise present on the internal reference, which, in turn, significantly reduces output noise. If output noise is not a concern, this input may be left unconnected. Larger capacitor values may be used, but the result is a longer time period to rated output voltage when power is initially applied.
4.2
Output Capacitor
A 1 F (min) capacitor from VOUT to ground is required. The output capacitor should have an Effective Series Resistance (ESR) of 0.01 to 5 for VOUT 2.5V, and 0.05. to 5 for VOUT < 2.5V. Ceramic, tantalum or aluminum electrolytic capacitors can be used. When using ceramic capacitors, X5R and X7R dielectric material are recommended due to their stable tolerance over temperature. However, other dielectrics can be used as long as the minimum output capacitance is maintained.

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
The PD equation can be used in conjunction with the PDMAX equation to ensure that regulator thermal operation is within limits. For example: Given: VINMAX VOUTMIN TJMAX TAMAX Find: 1. Actual power dissipation 2. Maximum allowable dissipation Actual power dissipation: P D = ( V INMAX - V OUTMIN )I LMAX = [ ( 3.0 x 1.1 ) - ( 2.7 x 0.975 ) ]40 x 10 = 26.7mW Maximum allowable power dissipation: T JMAX - T AMAX P DMAX = ------------------------------------- JA = 125 - 55 -------------------220 = 318mW In this example, the TC2014 dissipates a maximum of only 26.7 mW; far below the allowable limit of 318 mW. In a similar manner, the PD and PDMAX equations can be used to calculate maximum current and/or input voltage limits.

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% = +125C = +55C
ILOADMAX = 40 mA
5.2
Power Dissipation
The amount of power the regulator dissipates is primarily a function of input voltage, output voltage and output current. The following equation is used to calculate worst-case power dissipation.
EQUATION 5-1:
P D ( V INMAX - V OUTMIN )I LMAX Where: PD VINMAX ILMAX = Worst-case actual power dissipation = Maximum voltage on VIN = Maximum output (load) current
VOUTMIN = Minimum regulator output voltage
The maximum allowable power dissipation (PDMAX) is a function of the maximum ambient temperature (TAMAX), the maximum allowable die temperature (TJMAX) (+125C) 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.
