Package Type
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 con-
struction eliminates wasted ground current, signifi-
cantly extending battery life. Total supply current is
typically 80
μ
A at full load (20 to 60 times lower than in
bipolar regulators
).
TC2117 key features include ultra low noise, very low
dropout voltage (typically 450mV at full load), and fast
response to step changes in load. The TC2117 incor-
porates both over-temperature and over-current pro-
tection. The TC2117 is stable with an output capacitor
of only 1
μ
F and has a maximum output current of
800mA. This device is available in 3-Pin SOT-223, and
3-Pin DDPAK packages.
