General Description
The TC1014/TC1015/TC1185 are high accuracy
(typically ±0.5%) CMOS upgrades for older (bipolar)
Low Dropout Regulators (LDOs) 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 50 µA at full load (20 to 60 times
lower than in bipolar regulators).
The devices’ key features include ultra low-noise
operation (plus optional Bypass input), fast response to
step changes in load, and very low dropout voltage,
typically 85 mV (TC1014), 180 mV (TC1015), and
270 mV (TC1185) at full-load. Supply current is
reduced to 0.5 µA (max) and V
the shutdown input is low. The devices incorporate both
overtemperature and overcurrent protection.
The TC1014/TC1015/TC1185 are stable with an output
capacitor of only 1 µF and have a maximum output
current of 50 mA, 100 mA and 150 mA, respectively.
For higher output current regulators, please see the
