TC1173-2 2/2/00 TelCom Semiconductor reserves the right to make changes in the circuitry and specifications of its devices.
GENERAL DESCRIPTION
The TC1173 is a precision output (typically
±
0.5%)
CMOS low dropout regulator. Total supply current is typi-
cally 50
μ
A 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 0.05
μ
A (typical)
and V
OUT
and 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 1
μ
F and has a maximum output current of
300mA.
