TC1173

300mA CMOS LDO with Shutdown, ERROR Output and Bypass

FEATURES

GENERAL DESCRIPTION

■ Extremely Low Supply Current for Longer Battery

Life!

■ Very Low Dropout Voltage

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

CMOS low dropout regulator. Total supply current is typi-

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

regulators!).

■ Guaranteed 300mA Output

■ Standard or Custom Output Voltages

■ 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

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 V_OUTand ERROR fall to zero when the shutdown input

is low.

APPLICATIONS

■ Battery-Operated Systems

■ Portable Computers

■ Medical Instruments

■ Instrumentation

■ Cellular / GSM / PHS Phones

■ Linear Post-Regulator for SMPS

■ Pagers

The TC1173 incorporates both over-temperature and

over-currentprotection.TheTC1173isstablewithanoutput

capacitor of only 1µF and has a maximum output current of

300mA.
