TC1173

300mA CMOS LDO with Shutdown ERROR Output and Bypass

Features

General Description

•

Extremely Low Supply Current for Longer Battery Life

The TC1173 is a precision output (typically ±0.5%)

CMOS low dropout regulator. Total supply current is

typically 50µA at full load (20 to 60 times lower than in

bipolar regulators).

• Very Low Dropout Voltage

• 300mA Output Current

• Standard or Custom Output Voltages

TC1173 key features include ultra low noise operation

(plus optional Bypass input); very low dropout voltage

(typically 240mV at full load) and internal feed-forward

compensation for fast response to step changes in

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

TC1173 is out-of-regulation (due to a low input voltage

or excessive output current). ERROR can be set as a

low battery warning or as a processor RESET signal

(with the addition of an external RC network). Supply

current is reduced to 0.05µA (typical) and VOUT and

ERROR fall to zero when the shutdown input is low.

• ERROR Output Can Be Used as a Low Battery

Detector or Processor Reset Generator

• Power Saving Shutdown Mode

• Bypass Input for Ultra Quiet Operation

• Over Current and Over Temperature Protection

• Space-Saving MSOP Package Option

Applications

• Battery Operated Systems

• Portable Computers

• Medical Instruments

• Instrumentation

The TC1173 incorporates both over temperature and

over current protection. The TC1173 is stable with an

output capacitor of only 1µF and has a maximum

output current of 300mA.

• Cellular/GSM/PHS Phones

• Linear Post-Regulators for SMPS

• Pagers
