GENERAL DESCRIPTION  
The ADP165/ADP166 are very low quiescent current, low  
dropout (LDO), linear regulators that operate from 2.2 V to 5.5 V  
and provide up to 150 mA of output current. The low 120 mV  
dropout voltage at a 150 mA load improves efficiency and allows  
operation over a wide input voltage range.  
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 includes a switched resistor to  
discharge the output automatically when the LDO is disabled.  
The ADP166 is identical to the ADP165, but it does not include  
the output discharge function.  
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.  
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.
