General Description

The TC1174 is an adjustable output CMOS low dropout

regulator. Total supply current is typically 50

µAat full

load (20 to 60 times lower than in bipolar regulators).

TC1174 key features include ultra low noise operation

(plus optional Bypass input); very low dropout voltage

(typically 270mV at full load) and internal feed-forward

compensation for fast response to step changes in

load. Supply current is reduced to 0.05

µA (typical) and

VOUT falls to zero when the shutdown input is low.

The TC1174 incorporates both over temperature and

over current protection. The TC1174 is stable with an

output capacitor of only 1

µF and has a maximum

output current of 300mA.
