Data Sheet
THEORY OF OPERATION
The ADP150 is an ultralow noise, low quiescent current, low
dropout linear regulator that operates from 2.2 V to 5.5 V and
can provide up to 150 mA of output current. Drawing a low 220 μA
of quiescent current (typical) at full load makes the ADP150 ideal
for battery-operated portable equipment. Shutdown current
consumption is typically 200 nA.
Using new innovative design techniques, the ADP150 provides
superior noise performance for noise sensitive analog and
RF applications without the need for a noise bypass capacitor.
The ADP150 is also optimized for use with small 1 μF ceramic
capacitors.
ADP150
Internally, the ADP150 consists of a reference, an error amplifier,
a feedback voltage divider, and a PMOS pass transistor. Output
current is delivered via the PMOS pass device that is controlled
by the error amplifier. The error amplifier compares the reference
voltage with the feedback voltage from the output and amplifies
the difference. If the feedback voltage is lower than the reference
voltage, the gate of the PMOS device is pulled lower, allowing
more current to pass and increasing the output voltage. If the
feedback voltage is higher than the reference voltage, the gate of
the PMOS device is pulled higher, allowing less current to pass
and decreasing the output voltage.
The ADP150 is available in 14 output voltage options, ranging

VOUT
from 1.8 V to 3.3 V. The ADP150 uses the EN pin to enable and
disable the VOUT pin under normal operating conditions. When
EN is high, VOUT turns on, and when EN is low, VOUT turns
off. For automatic startup, EN can be tied to VIN.
