TC1070/TC1071/TC1187

50mA, 100mA and 150mA Adjustable CMOS LDOs with Shutdown

Features

General Description

• Zero Ground Current for Longer Battery Life

• Adjustable Output Voltage

The TC1070, TC1071 and TC1187 are adjustable

LDOs designed to supersede a variety of older (bipolar)

voltage regulators. Total supply current is typically

50µA at full load (20 to 60 times lower than in bipolar

regulators).

• Very Low Dropout Voltage

• Choice of 50mA (TC1070), 100mA (TC1071) and

150mA (TC1187) Output

The devices’ key features include ultra low noise

operation, very low dropout voltage – typically 85mV

(TC1070); 180mV (TC1071); and 270mV (TC1187) at

full load, and fast response to step changes in load.

Supply current is reduced to 0.5µA (max) when the

shutdown input is low. The devices incorporate both

over-temperature and over-current protection. Output

voltage is programmed with a simple resistor divider

• Power-Saving Shutdown Mode

• Over Current and Over Temperature Protection

• Space-Saving 5-Pin SOT-23A Package

• Pin Compatible with Bipolar Regulators

Applications

• Battery Operated Systems

• Portable Computers

• Medical Instruments

• Instrumentation

from V

to ADJ to GND.

OUT

The TC1070, TC1071 and TC1187 are stable with an

output capacitor of only 1µF and have a maximum

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

respectively. For higher output versions, please see the
