General Description
The TC2117 is a fixed, high accuracy (typically ±0.5%)
CMOS low dropout regulator. Designed specifically for
battery operated systems, the TC2117’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).
TC2117 key features include ultra low noise, very low
dropout voltage (typically 450 mV at full load), and fast
response to step changes in load. The TC2117
incorporates both overtemperature and overcurrent
protection. The TC2117 is stable with an output
capacitor of only 1µF and has a maximum output
current of 800 mA. This device is available in 3-Pin
SOT-223, and 3-Pin DDPAK packages.
