GENERAL DESCRIPTION
The TC1015 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 TC1015’s CMOS construction eliminates wasted
ground current, significantly extending battery life. Total
supply current is typically 50µA at full load (20 to 60 times
lower than in bipolar regulators!).
TC1015 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. Supply
current is reduced to 0.05µA and VOUT is disabled when the
shutdown input is low. The TC1015 also incorporates both
over-temperature and over-current protection.
The TC1015 is stable with an output capacitor of only
1µF and has a maximum output current of 100mA. For
higher output versions, please see the TC1107, TC1108,
TC1173 (IOUT = 300mA) data sheets.
