TC1014/TC1015/TC1185
General Description
The TC1014/TC1015/TC1185 are high accuracy
(typically ±0.5%) CMOS upgrades for older (bipolar)
low dropout regulators such as the LP2980. Designed
specifically for battery-operated systems, the devices’
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).
The devices’ key features include ultra low noise oper-
ation (plus optional Bypass input), fast response to step
changes in load, and very low dropout voltage –
typically 85mV (TC1014); 180mV (TC1015); and
270mV (TC1185) at full load. Supply current is reduced
to 0.5µA (max) and V
shutdown input is low. The devices incorporate both
over-temperature and over-current protection.
The TC1014/TC1015/TC1185 are stable with an output
capacitor of only 1µF and have a maximum output
current of 50mA, 100mA and 150mA, respectively. For
higher output current regulators, please see the
