GENERAL DESCRIPTION
The TC1072 is a high accuracy (typically
±
0.5%) CMOS
upgrade for older (bipolar) low dropout regulators. Designed
specifically for battery-operated systems, the TC1072’s
50mA CMOS LDO WITH SHUTDOWN, ERROR OUTPUT AND V
REF
BYPASS
TYPICAL APPLICATION
TelCom Semiconductor reserves the right to make changes in the circuitry and specifications ot its devices.
CMOS construction eliminates wasted ground current, sig-
nificantly extending battery life. Total supply current is
typically 50
μ
A at full load (20 o 60 imes ower han n bipolar
regulators).
TC1072 key features include ultra low noise operation
(plus optional Bypass input); very low dropout voltage (typi-
cally 100mV at full load) and internal feed-forward compen-
sation for fast response to step changes in load. An error
output (ERROR) is asserted when the TC1072 is out-of-
regulation (due to a low input voltage or excessive output
current). ERROR can be used as a low battery warning or as
a processor RESET signal (with the addition of an external
RC network). Supply current is reduced to less than 1
μ
A,
and both V
OUT
and ERROR are disabled when the shutdown
input is low. The TC1072 incorporates both over-tempera-
ture and over-current protection.
The TC1072 is stable with an output capacitor of only
1
μ
F and has a maximum output current of 50mA. For higher
output current versions, please see the TC1107, TC1108
and TC1073 (I
OUT
= 300mA) data sheets.
