General Description
The TC59 is a low dropout, negative output voltage
regulator designed specifically for battery-operated
systems. Its full CMOS construction eliminates the
wasted ground current typical of bipolar LDOs. This
reduced supply current significantly extends battery
life, particularly when the TC59 is operated in dropout.
Other TC59 key features include low supply current
(typically 3.0µA) and low dropout operation (typically
120mV at 50mA). The TC59 is packaged in a small
3-Pin SOT-23A package.
