General Description

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

significantly extending battery life. Total supply current

is typically 50µA 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 85mV,

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

response to step changes in load. Supply current is

reduced to 0.5µA (max) and V

the shutdown input is low. The devices incorporate both

over temperature and over current protection.

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,

TC1108 and TC1173 (I
