General Description
The TC1268 is a fixed output, fast turn-on, high
accuracy
(typically
±0.5%)
regulator. Designed specifically for battery-operated
systems, the TC1268’s CMOS construction eliminates
wasted ground current, significantly extending battery
life. Total supply current is typically 80
μ
A at full load (20
to 60 times lower than in bipolar regulators).
CMOS
low
dropout
TC1268’s key features include ultra low noise, very low
dropout voltage (typically 350mV at full load), and
fast response to step changes in load. The TC1268
also has a fast wake-up response time (5
μ
sec typically)
when
released
from
shutdown.
incorporates both over temperature and over current
protection. The TC1268 is stable with an output
capacitor of only 1
μ
F and has a maximum output
current of 500mA.
