TC1223/TC1224

50mA and 100mA CMOS LDOs with Shutdown

General Description

Features

• Extremely Low Ground Current for Longer Battery

Life

The TC1223 and TC1224 are high accuracy (typically

±0.5%) CMOS upgrades for older (bipolar) low dropout

regulators such as the LP2980. Designed specifically

for battery-operated systems, the devices’ CMOS

construction eliminates wasted ground current,

significantly extending battery life. 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 and 100mA Output (TC1223,

TC1224, Respectively)

• High Output Voltage Accuracy

• Standard or Custom Output Voltages

• Power Saving Shutdown Mode

The devices’ key features include ultra low noise

operation; very low dropout voltage (typically 85mV,

TC1223 and 180mV, TC1224 at full load) and fast

response to step changes in load. Supply current is

• Over Current and Over Temperature Protection

• Space-Saving 5-Pin SOT-23A Package

• Pin Compatible Upgrades for Bipolar Regulators

reduced to 0.5µA (max) and V

the shutdown input is low. The devices incorporate both

over temperature and over current protection.

Applications

• Battery Operated Systems

• Portable Computers

• Medical Instruments

• Instrumentation

The TC1223 and TC1224 are stable with an output

capacitor of only 1µF and have a maximum output

current of 50mA and 100mA respectively. For higher

output current versions, please see the TC1107,

• Cellular/GSM/PHS Phones

• Linear Post-Regulators for SMPS

• Pagers

TC1108 and TC1173 (I

= 300mA) data sheets.
