TC2014/2015/2185

50 mA, 100 mA, 150 mA CMOS LDOs with

Shutdown and Reference Bypass

Features

General Description

• Low Supply Current: 80 µA (Max)

The TC2014, TC2015 and TC2185 are high-accuracy

(typically ±0.4%) CMOS upgrades for bipolar low drop-

out regulators, such as the LP2980. Total supply cur-

rent is typically 55 µA; 20 to 60 times lower than in

bipolar regulators.

• Low Dropout Voltage: 140 mV (Typ) @ 150 mA

• High Output Voltage Accuracy: ±0.4% (Typ)

• Standard or Custom Output Voltages

• Power-Saving Shutdown Mode

• Reference Bypass Input for Ultra Low-Noise

Operation

• Fast Shutdown Response Time: 60 µsec (Typ)

• Over-Current Protection

• Space-Saving 5-Pin SOT-23A Package

• Pin Compatible Upgrades for Bipolar Regulators

• Wide Operating Temperature Range:

-40°C to +125°C

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

falls to zero when

OUT

the shutdown input is low. The devices also incorporate

over-current protection.

The TC2014, TC2015 and TC2185 are stable with an

output capacitor of 1 µF and have a maximum output

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

For higher output versions, see the TC1107

(DS21356), TC1108 (DS21357) and TC1173
