GENERAL DESCRIPTION
upgrade for older (bipolar) low dropout regulators such as
the LP2980. Designed specifically for battery-operated sys-
tems, the TC1015’s CMOS construction eliminates wasted
ground current, significantly extending battery life. Total
supply current is typically 50 A at full load ( 20 to 60 times
lower than in bipolar regulators !).
(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. Supply
current is reduced to 0.05 A and V
shutdown input is low. The TC1015 also incorporates both
over-temperature and over-current protection.
1 F and has a maximum output current of 100mA. For
