ADP165ACPZN-3.3-R7
LDO Regulator Pos 3.3V 0.15A 6Pin LFCSP T/R
Product Details
The ADP165/ADP166 are very low quiescent current, low dropout, linear regulator that operate from 2.2 V to 5.5 V and provides up to 150 mA of output current. The low 120 mV dropout voltage at 150 mA load improves efficiency and allows operation over a wide input voltage range.
The ADP165/ADP166 are specifically designed for stable operation with a tiny 1 µF ± 30% ceramic input and output capacitors to meet the requirements of high performance, space-constrained applications.
The ADP165/ADP166 are available in seven fixed output voltage options, ranging from 1.2 V to 3.3 V, and an adjustable output option. The ADP165 also include a switched resistor to discharge the output automatically when the LDO is disabled. The ADP166 is identical to the ADP165, but does not include the output discharge function.
Short-circuit and thermal overload protection circuits prevent damage in adverse conditions. The ADP165/ADP166 are available in a tiny 5-lead TSOT, a 6-lead LFCSP and a 4-ball, 0.5 mm pitch WLCSP package for the smallest footprint solution to meet a variety of portable power applications.
