TC1054/TC1055/TC1186

50 mA, 100 mA and 150 mA CMOS LDOs with Shutdown and ERROR Output

Features

General Description

• Low Ground Current for Longer Battery Life

• Low Dropout Voltage

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 minimizes ground current, extending

battery life. Total supply current is typically 50 µA at full

load (20 to 60 times lower than in bipolar regulators).

• Choice of 50 mA (TC1054), 100 mA (TC1055)

and 150 mA (TC1186) Output

• High Output Voltage Accuracy

• Standard or Custom Output Voltages:

- 1.8V, 2.5V, 2.6V, 2.7V, 2.8V, 2.85V, 3.0V,

3.3V, 3.6V, 4.0V, 5.0V

The devices’ key features include low noise operation,

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 (maximum), with both

V_OUTand ERROR disabled when the shutdown input is

low. The devices incorporate both overtemperature

and over-current protection.

• Power-Saving Shutdown Mode

• ERROR Output Can Be Used as a Low-Battery

Detector or Microcontroller-Reset Generator

• Overcurrent and Overtemperature Protection

• 5-Pin SOT-23 Package

• Pin-Compatible Upgrades for Bipolar Regulators

Applications

• Battery Operated Systems

• Portable Computers

• Medical Instruments

• Instrumentation

The TC1054, TC1055 and TC1186 are stable with an

output capacitor of only 1 µF, and have a maximum

output current of 50 mA, 100 mA and 150 mA,

respectively. For higher output current regulators,

please refer to the TC1173 (I_OUT= 300 mA) data sheet

(DS21632).

• Cellular/GSM/PHS Phones

• Linear Post-Regulators for SMPS

• Pagers
