GENERAL DESCRIPTION
The TC1014 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 TC1014’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!).
TC1014 key features include ultra low-noise operation
(plus optional Bypass input); very low dropout voltage
(typically 95mV at full load) and internal feed-forward com-
pensation for fast response to step changes in load. Supply
current is reduced to less than 1µA when the shutdown input
is low. The TC1014 also incorporates both over-tempera-
ture and over-current protection.
The TC1014 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.
