The low 195 mV dropout voltage at 150 mA load improves efficiency and allows operation over a wide input voltage range. The ADP160/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 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 ADP161 is available as an adjustable output voltage regulator. It is only available in a 5-lead TSOT package. Short-circuit and thermal overload protection circuits prevent damage in adverse conditions. The ADP160 is available in a tiny 5-lead TSOT and a 4-ball, 0.5 mm pitch WLCSP package for the smallest footprint solution to meet a variety of portable power applications. |
