TheADP160/ADP161/ADP162/ADP163are ultralow quiescentcurrent, low dropout, linear regulators that operate from 2.2 Vto 5.5 V and provide up to 150 mA of output current. The low195 mV dropout voltage at 150 mA load improves efficiency andallows operation over a wide input voltage range.
The ADP16x are specifically designed for stable operation withtiny 1 μF ± 30% ceramic input and output capacitors to meetthe requirements of high performance, space-constrainedapplications.
The ADP160 is available in 15 fixed output voltage options,ranging from 1.2 V to 4.2 V. The ADP160/ADP161 also includea switched resistor to discharge the output automatically when the LDO is disabled. The ADP162ACBZ-1.2-R7 is identical to the ADP160but does not include the output discharge function.The ADP161and ADP163 are available as a adjustable outputvoltage regulators. They are only available in a 5-lead TSOTpackage. The ADP163 is identical to the ADP161 but does notinclude the output discharge function.
Short-circuit and thermal overload protection circuits preventdamage in adverse conditions. The ADP160 and ADP162ACBZ-1.2-R7 areavailable in a tiny 5-lead TSOT and a 4-ball, 0.5 mm pitchWLCSP package for the smallest footprint solution to meet avariety of portable power applications.
