General Description
The AP2201 is a 150mA output current fixed voltage
regulator designed to provide very low noise (45
Vrms
at 80Hz-100KHz), ultra low dropout voltage (typically
165mV at 150mA), very low quiescent current (1
A
maximum) and excellent power supply ripple rejection
(PSRR 75dB at 100Hz) in battery powered applica-
tions, such as handsets and PDAs and in noise sensitive
applications, such as RF electronics.
The AP2201 also features individual logic compatible
enable/shutdown control inputs, a low power shutdown
mode for extended battery life, over current protection,
over temperature protection, as well as reversed-bat-
tery protection.
The output capacitor of 1.0
F minimum and 2.2
F
minimum near its pin are recommended when C
BYP
is
not used and when C
BYP
is 470pF respectively. The
output capacitor should have 5
or less ESR, tantalum
or aluminium electrolytic capacitors are adequate.
Bypass capacitor is connected to the internal voltage
reference to quiet noise. Its recommended value is
from 470pF to 1nF. If output noise is not a major con-
cern and rapid turn-on is necessary, omit C
BYP
and
leave BYP open.
The AP2201 has 2.6V, 2.8V and 3.0V versions now.
The AP2201 is available in space saving 5-pin SOT-
23-5 package.

Note 1:
Stresses greater than those listed under "Absolute Maximum Ratings" may cause permanent damage to the device.
These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated
under "Recommended Operating Conditions" is not implied. Exposure to "Absolute Maximum Ratings" for extended periods
may affect device reliability.

Recommended Operating Conditions
Note 2: Absolute maximum ratings indicate limits beyond which damage to the component may occur. Electrical specifica-
tions do not apply when operating the device outside of its operating ratings. The maximum allowable power dissipation is a
function of the maximum junction temperature, T
J(max),
the junction-to-ambient thermal resistance,
JA,
and the ambient tem-
perature, T
A.
The maximum allowable power dissipation at any ambient temperature is calculated using: P

)/
JA.
Exceeding the maximum allowable power dissipation will result in excessive die temperature, and the regulator will
go into thermal shutdown.
