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 50A 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

reduced to 0.5A (max) and V_OUTfalls to zero when

the shutdown input is low. The devices incorporate both

over temperature and over current protection.

• Over Current and Over Temperature Protection

• Space-Saving 5-Pin SOT-23A Package

• Pin Compatible Upgrades for Bipolar Regulators

Applications

• Battery Operated Systems

• Portable Computers

• Medical Instruments

• Instrumentation

The TC1223 and TC1224 are stable with an output

capacitor of only 1F and have a maximum output

current of 50mA and 100mA respectively. For higher

output current versions, please see the TC1107,

TC1108 and TC1173 (I_OUT= 300mA) data sheets.

• Cellular/GSM/PHS Phones

• Linear Post-Regulators for SMPS

• Pagers
