Description
The TC1265 is a fixed-output, high-accuracy (typically
±0.5%) CMOS low dropout regulator. Designed
specifically for battery-operated systems, the TC1265’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).
Key features of the TC1265 include ultra low noise
operation, very low dropout voltage (typically 450 mV
at full load) and fast response to step changes in load.
The TC1265 incorporates both overtemperature and
overcurrent protection. The TC1265 is stable with an
output capacitor of only 1 µF and has a maximum
output current of 800 mA. It is available in 8-Pin SOIC,
5-Pin TO-220 and 5-Pin DDPAK packages.
