ADP150 Ultralow Noise, 150 mA CMOS Linear Regulator
Applications
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.
