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.

Note:
The graphs and tables provided following this note are a statistical summary based on a limited number of
samples and are provided for informational purposes only. The performance characteristics listed herein are
not tested or guaranteed. In some graphs or tables, the data presented may be outside the specified
operating range (e.g., outside specified power supply range) and therefore outside the warranted range.
