TC1268 pdf datasheet

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).
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.
