General Description

The TC1262 is a fixed output, high accuracy (typically

±0.5%) CMOS low dropout regulator. Designed

specifically for battery-operated systems, the TC1262’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).

TC1262 key features include ultra low noise operation,

very low dropout voltage (typically 350 mV at full load),

and fast response to step changes in load.

The TC1262 incorporates both over temperature and

over current protection. The TC1262 is stable with an

output capacitor of only 1 μF and has a maximum

output current of 500 mA. It is available in

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

packages.
