TC1073
PRELIMINARY INFORMATION
TC1073-01 6/5/97
100mA CMOS LDO WITH SHUTDOWN,
ERROR OUTPUT AND V
REF
BYPASS
GENERAL DESCRIPTION
The TC1073 is a high accuracy (typically
±
0.5%) CMOS
upgrade for older (bipolar) low dropout regulators such as
the LP2980. Designed specifically for battery-operated sys-
tems, the TC1073’s CMOS construction eliminates wasted
ground current, significantly extending battery life. Total
supply current is typically 50
μ
A at full load (20 to 60 times
lower than in bipolar regulators).
TC1073 key features include ultra low noise operation
(plus optional Bypass input); very low dropout voltage (typi-
cally 200mV 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 TC1073 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 TC1073 incorporates both over-tempera-
ture and over-temeprature protection.
The TC1073 is stable with an output capacitor of only
1
μ
F and has a maximum output current of 100mA. For
higher output current versions, please see the TC1107,
TC1108 (I
OUT
= 300mA) data sheets.
