TC1265

800mA Fixed Output CMOS LDO with Shutdown

FEATURES

GENERAL DESCRIPTION

■ Very Low Dropout Voltage

■ Guaranteed 800mA Output

■ High Output Voltage Accuracy

■ Standard or Custom Output Voltages

■ Over-Current and Over-Temperature Protection

■ SHDN Input for Active Power Management

■ ERROR Output to Detect Low Battery (SOIC Only)

The TC1265 is a fixed output, high accuracy (typically

±0.5%) CMOS low dropout regulator. Designed specifically

for battery-operated systems, the TC1265’s CMOS con-

struction eliminates wasted ground current, significantly

extending battery life. Total supply current is typically 80µA

at full load (20 to 60 times lower than in bipolar regulators!).

TC1265 key features include ultra low noise, very low

dropout voltage (typically 450mV at full load), and fast

responsetostepchangesinload. TheTC1265incorporates

both over-temperature and over-current protection. The

TC1265 is stable with an output capacitor of only 1µF and

has a maximum output current of 800mA. It is available in 8-

Pin SOIC, 5-Pin TO-220, and 5-Pin DDPAK packages.

APPLICATIONS

■ Battery-Operated Systems

■ Portable Computers

■ Medical Instruments

■ Instrumentation

■ Cellular / GSM / PHS Phones

■ Linear Post-Regulator for SMPS

■ Pagers
