ADP162AUJZ-3.1-R7

LDO Regulator Pos 3.1V 0.15A 5Pin TSOT T/R

GENERAL DESCRIPTION

The ADP160/ADP161/ADP162/ADP163 are ultralow quiescent current, low dropout, linear regulators that operate from 2.2 V to 5.5 V and provide up to 150 mA of output current. The low

195 mV dropout vol tage at 150 mA load improves efficiency and allows operation over a wide input voltage range.

The ADP16x are specifically designed for stable operation with a tiny 1 µF ± 30% ceramic input and output capacitors to meet the requirements of high performance, space-constrained

applications.

The ADP160 is available in 15 fixed output voltage options, ranging from 1.2 V to 4.2 V . The ADP160/ADP161 also include a switched resistor to discharge the output automatically when the LDO is disabled. The ADP162 is identical to the ADP160 but does not include the output discharge function.
