TC1014/TC1015/TC1185

50 mA, 100 mA and 150 mA CMOS LDOs with Shutdown

and Reference Bypass

Features:

General Description

• Low Supply Current (50 µA, typical)

• Low Dropout Voltage

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).

• Choice of 50 mA (TC1014), 100 mA (TC1015)

and 150 mA (TC1185) Output

• High Output Voltage Accuracy

• Standard or Custom Output Voltages

• Power-Saving Shutdown Mode

• Reference Bypass Input for Ultra Low-Noise

Operation

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_OUTfalls to zero when

the shutdown input is low. The devices incorporate both

overtemperature and overcurrent protection.

• Overcurrent and Overtemperature Protection

• Space-Saving 5-Pin SOT-23 Package

• Pin-Compatible Upgrades for Bipolar Regulators

• Standard Output Voltage Options:

- 1.8V, 2.5V, 2.6V, 2.7V, 2.8V, 2.85V, 3.0V,

3.3V, 3.6V, 4.0V, 5.0V

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

TC1107 (DS21356), TC1108 (DS21357), TC1173

(DS21362) (I_OUT= 300 mA) data sheets.

Applications:

• Battery-Operated Systems

• Portable Computers

• Medical Instruments
