General Description

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

in bipolar regulators).

TC1264 key features include ultra low noise operation,

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

and fast response to step changes in load.

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 800mA. It is available in 3-Pin

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