GENERAL DESCRIPTION  
The ADP122/ADP123 are low quiescent current, low dropout  
linear regulators. They are designed to operate from an input  
voltage between 2.3 V and 5.5 V and to provide up to 300 mA of  
output current. The low 85 mV dropout voltage at a 300 mA load  
improves efficiency and allows operation over a wide input  
voltage range.

(Not to Scale)  
The low 170 μA of quiescent current at full load makes the ADP122  
ideal for battery-operated portable equipment.  
NC = NOT CONNECT. THIS PIN CAN BE LEFT FLOATING  
OR CONNECTED TO GROUND.  
The ADP122 is capable of 31 fixed output voltages from 1.75 V  
to 3.3 V. The ADP123 is the adjustable version of the device and  
allows the output voltage to be set between 0.8 V and 5.0 V by  
an external voltage divider.  
Figure 4. ADP123 with Adjustable Output Voltage (LFCSP Version)  
The ADP122/ADP123 have an internal soft start that gives a  
constant start-up time of 350 µs. Short-circuit protection and  
thermal overload protection circuits prevent damage in adverse  
conditions. The ADP122/ADP123 are available in a tiny, 5-lead  
TSOT package and 6-lead LFCSP package for the smallest  
footprint solution to meet a variety of portable applications.  
The ADP122/ADP123 are specifically designed for stable operation  
with tiny 1 µF ceramic input and output capacitors to meet the  
requirements of high performance, space constrained applications.
