ADP150AUJZ-1.8-R7

线性稳压器 Ultralow Noise 150mA CMOS

Ultralow Noise,  150 mA CMOS Linear Regulator

GENERAL DESCRIPTION ADP150AUJZ-1.8-R7

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.
