General Description
The TC1173 is a precision output (typically ±0.5%)
CMOS low dropout regulator. Total supply current is
typically 50µA at full load (20 to 60 times lower than in
bipolar regulators).
TC1173 key features include ultra low noise operation
(plus optional Bypass input); very low dropout voltage
(typically 240mV at full load) and internal feed-forward
compensation for fast response to step changes in
load. An error output (ERROR) is asserted when the
TC1173 is out-of-regulation (due to a low input voltage
or excessive output current). ERROR can be set as a
low battery warning or as a processor RESET signal
(with the addition of an external RC network). Supply
current is reduced to 0.05µA (typical) and V
ERROR fall to zero when the shutdown input is low.
The TC1173 incorporates both over temperature and
over current protection. The TC1173 is stable with an
output capacitor of only 1µF and has a maximum
output current of 300mA.
