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.

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.

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.

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.
