GENERAL DESCRIPTION  
The ADP150 is an ultralow noise (9 µV), low dropout, linear  
regulator that operates from 2.2 V to 5.5 V and provides up to  
150 mA of output current. The low 105 mV dropout voltage at  
150 mA load improves efficiency and allows operation over a  
wide input voltage range.  
The ADP150 is 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 ADP150 is available in 14 fixed output voltage options,  
ranging from 1.8 V to 3.3 V.  
Using an innovative circuit topology, the ADP150 achieves ultralow  
noise performance without the necessity of an additional noise  
bypass capacitor, making it ideal for noise sensitive analog and  
RF applications. The ADP150 also achieves ultralow noise  
performance without compromising PSRR or line and load  
transient performance. The ADP150 offers the best combination  
of ultralow noise and quiescent current consumption to maximize  
battery life in portable applications.  
Short-circuit and thermal overload protection circuits prevent  
damage in adverse conditions. The ADP150 is available in tiny  
5-lead TSOT and 4-ball, 0.4 mm pitch WLCSP packages for the  
smallest footprint solution to meet a variety of portable power  
applications.
