TC1268

500mA Fixed Output, Fast Response CMOS LDO with Shutdown

Features

General Description

• Very Low Dropout Voltage

The TC1268 is a fixed output, fast turn-on, high

accuracy (typically ±0.5%) CMOS low dropout

regulator. Designed specifically for battery-operated

systems, the TC1268’s CMOS construction 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).

• 500mA Output Current

• 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

• 5µsec (typical) Wake-up Time from SHDN

TC1268’s key features include ultra low noise, very low

dropout voltage (typically 350mV at full load), and

fast response to step changes in load. The TC1268

also has a fast wake-up response time (5µsec typically)

when released from shutdown. The TC1268

incorporates both over temperature and over current

protection. The TC1268 is stable with an output

capacitor of only 1µF and has a maximum output

current of 500mA.
