GENERAL DESCRIPTION
The ADP151 is an ultralow noise, low dropout linear regulator
that operates from 2.2 V to 5.5 V and provides up to 200 mA
of output current. The low 140 mV dropout voltage at 200 mA
load improves efficiency and allows operation over a wide input
voltage range.
Using an innovative circuit topology, the ADP151 achieves
ultralow noise performance without the necessity of a bypass
capacitor, making it ideal for noise-sensitive analog and RF
applications. The ADP151 also achieves ultralow noise per-
formance without compromising PSRR or transient line and
load performance. The low 265 μA of quiescent current at
200 mA load makes the ADP151 suitable for battery-operated
portable equipment.
The ADP151 also includes an internal pull-down resistor on the
EN input.

The ADP151 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 ADP151 is capable of 16 fixed output voltage options,
ranging from 1.1 V to 3.3 V.
Short-circuit and thermal overload protection circuits prevent
damage in adverse conditions. The ADP151 is available in tiny
5-lead TSOT, 6-lead LFCSP, and 4-ball, 0.4 mm pitch, halide-free
WLCSP packages for the smallest footprint solution to meet a
variety of portable power application requirements.
