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
eliminates
significantly extending battery life. Total supply current
is typically 50
μ
A at full load (20 to 60 times lower than
in bipolar regulators).

current,
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
μ
A (max) and V

falls to zero when
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 1
μ
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

= 300mA) data sheets.
