Package Type

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 3.0

µA) and low dropout operation (typically

120mV at 50mA). The TC59 is packaged in a small

3-Pin SOT-23A package.
