General Description
The TC1174 is an adjustable output CMOS low dropout
regulator. Total supply current is typically 50
μ
A at 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
μ
A (typical) and
V
OUT
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
μ
F and has a maximum
output current of 300mA.
