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 50 µA 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 85 mV (TC1054); 180 mV (TC1055); and 270 mV (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 0.5 µA (max) and both VOUT and ERROR are disabled when the shutdown input is low. The devices incorporate both overtemperature and over-current protection. The TC1054, TC1055, and TC1186 are stable with an output capacitor of only 1 µF and have a maximum output current of 50mA, 100mA, and 150mA, respectively. For higher output current regulators, please see the TC1173 (IOUT = 300 mA) data sheet. TYPICAL APPLICATION

NOTES: 1. VR is the regulator output voltage setting. For Example: VR = 2.5V, 2.7V, 2.85, 3.0V, 3.3V, 3.6V, 4.0V, 5.0V. 2. TC VOUT = VOUTMAX VOUTMIN x 106 VOUT x T 3. Regulation is measured at a constant junction temperature using low duty cycle pulse testing. Load regulation is tested over a load range from 0.1 mA to the maximum specified output current. Changes in output voltage due to heating effects are covered by the thermal regulation specification. 4. Dropout voltage is defined as the input to output differential at which the output voltage drops 2% below its nominal value. 5. Thermal Regulation is defined as the change in output voltage at a time T after a change in power dissipation is applied, excluding load or line regulation effects. Specifications are for a current pulse equal to ILMAX at VIN = 6V for T = 10 msec. 6. 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 Thermal Considerations section of this data sheet for more details. 7. Hysteresis voltage is referenced by VR. 8. Apply for Junction Temperatures of40°C to +85°C.

Description
Unregulated supply input. Ground terminal. Shutdown control input. The regulator is fully enabled when a logic high is applied to this input. The regulator enters shutdown when a logic low is applied to this input. During shutdown, output voltage falls to zero, ERROR is open circuited and supply current is reduced to 0.5 µA (max). Out-of-Regulation Flag. (Open drain output). This output goes low when VOUT is out-of-tolerance by approximately 5%. Regulated voltage output.
