The ADP162 is identical to the ADP160 current, low dropout, linear regulators that operate from 2.2 V but does not include the output discharge function. to 5.5 V and provide up to 150 mA of output current. The low The ADP161 and ADP163 are available as adjustable output voltage 195 mV dropout voltage at 150 mA load improves efficiency and regulators. They are only available in a 5-lead TSOT package. allows operation over a wide input voltage range. The ADP163 is identical to the ADP161 but does not include The ADP16x are specifically designed for stable operation with a the output discharge function. tiny 1 F 30% ceramic input and output capacitors to meet Short-circuit and thermal overload protection circuits prevent the requirements of high performance, space-constrained damage in adverse conditions. The ADP160 and ADP162 are applications. available in a tiny 5-lead TSOT and a 4-ball, 0.5 mm pitch The ADP160 is available in 15 fixed output voltage options, WLCSP package for the smallest footprint solution to meet a ranging from 1.2 V to 4.2 V. The ADP160/ADP161 also include variety of portable power applications. a switched resistor to discharge the output automatically when Rev.
