TC1072/TC1073

50mA and 100mA CMOS LDOs with Shutdown, ERROR Output and V_REFBypass

Features:

General Description

• 50 µA Ground Current for Longer Battery Life

• Very Low Dropout Voltage

The TC1072 and TC1073 are high accuracy (typically

±0.5%) CMOS upgrades for older (bipolar) low dropout

regulators. 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 (TC1072) and 100 mA (TC1073)

Output

• High Output Voltage Accuracy

• Standard or Custom Output Voltages

• Power-Saving Shutdown Mode

The devices’ key features include ultra low noise

operation (plus optional Bypass input); very low

dropout voltage (typically 85 mV, TC1072 and 180 mV,

TC1073 at full load) and fast response to step changes

in load. An error output (ERROR) is asserted when the

devices are out-of-regulation (due to a low input

voltage or excessive output current). ERROR can be

used as a low battery warning or as a processor

RESET signal (with the addition of an external RC

network). Supply current is reduced to 0.5 µA (max)

and both V_OUTand ERROR are disabled when the

shutdown input is low. The devices incorporate both

overtemperature and overcurrent protection.

• ERROR Output Can Be Used as a Low Battery

Detector or Processor Reset Generator

• Bypass Input for Ultra Quiet Operation

• Overcurrent and Overtemperature Protection

• Space-Saving 6-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

• Other output voltages are available. Please

contact Microchip Technology Inc. for details.

The TC1072 and TC1073 are stable with an output

capacitor of only 1 µF and have a maximum output

current of 50 mA, and 100 mA, respectively. For higher

output current versions, please see the TC1185,

TC1186, TC1187 (I_OUT= 150 mA) and TC1107,

TC1108 and TC1173 (I_OUT= 300 mA) data sheets.

Applications:

• Battery Operated Systems

• Portable Computers

• Medical Instruments

• Instrumentation

• Cellular/GSM/PHS Phones

• Linear Post-Regulators for SMPS

• Pagers
