General Description

The TC2014, TC2015 and TC2185 are high-accuracy

(typically ±0.4%) CMOS upgrades for bipolar Low

Drop-out Regulators (LDOs), such as the LP2980.

Total supply current is typically 55 µA; 20 to 60 times

lower than in bipolar regulators.

The key features of the device include low noise oper-

ation (plus bypass reference), low dropout voltage

– typically 45 mV for the TC2014, 90 mV for the

TC2015, and 140 mV for the TC2185, at full load – and

fast response to step changes in load. Supply current

is reduced to 0.5 µA (max) and V

the shutdown input is low. These devices also

incorporate overcurrent protection.

The TC2014, TC2015 and TC2185 are stable with an

output capacitor of 1 µF and have maximum output

currents of 50 mA, 100 mA and 150 mA, respectively.
