TC1264

800 mA Fixed-Output CMOS LDO with Shutdown

Features

Description

• Very Low Dropout Voltage

The TC1264 is a fixed output, high accuracy (typically

±0.5%) CMOS low dropout regulator. Designed

specifically for battery-operated systems, the TC1264’s

CMOS construction eliminates wasted ground current,

significantly extending battery life. Total supply current

is typically 80 µA at full load (20 to 60 times lower than

in bipolar regulators).

• 800 mA Output Current

• High Output Voltage Accuracy

• Standard or Custom Output Voltages

• Overcurrent and Overtemperature Protection

Applications

TC1264 key features include ultra low noise operation,

very low dropout voltage (typically 450 mV at full load),

and fast response to step changes in load.

• Battery Operated Systems

• Portable Computers

• Medical Instruments

• Instrumentation

The TC1264 incorporates both over temperature and

over current protection. The TC1264 is stable with an

output capacitor of only 1μF and has a maximum

output current of 800 mA. It is available in 3-Pin

SOT-223, 3-Pin TO-220 and 3-Pin DDPAK packages.

• Cellular/GSM/PHS Phones

• Linear Post-Regulators for SMPS

• Pagers
