ADP161 Description

The ADP161 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 voltage at 150 mA load improves efficiency and allows operation over a wide input voltage range.

The ADP161 are specifically designed for stable operation with tiny 1 μF ± 30% ceramic input and output capacitors to meet the requirements of high performance, space-constrained applications.

The ADP161 also include a switched resistor to discharge the output automatically when the LDO is disabled.

The ADP161 are available as a adjustable output voltage regulators. They are only available in a 5-lead TSOT package. The ADP163 is identical to the ADP161 but does not include the output discharge function.

Short-circuit and thermal overload protection circuits prevent damage in adverse conditions.
