TYPICAL APPLICATION

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 50
μ
A 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 1
μ
A 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
1
μ
F and has a maximum output current of 100mA. For
higher output versions, please see the TC1107, TC1108,
TC1173 (I
OUT
= 300mA) data sheets.
