The ADP160/ADP161/ADP162/ADP163 are 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 ADP160ACBZ-1.2-R7 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 ADP162 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 ADP160ACBZ-1.2-R7 and ADP162 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.
