TC1268

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 device'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).

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. It also has a fast wake-up response time (5µsec typically) when released from shutdown. It 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.
