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 80 µA 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 450 mV 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 1 µF and has a maximum
output current of 800 mA. It is available in 3-pin
SOT-223, 3-pin TO-220 and 3-pin DDPAK packages.
