150mA RF ULDO REGULATOR AP2202
Preliminary Datasheet

BCD Semiconductor Manufacturing Limited
General Description
The AP2202 is a 150mA ULDO regulator which pro-
vides very low noise (45
μ
Vrms at 80Hz-100KHz),
ultra low dropout voltage (typically 165mV at
150mA), very low quiescent current (1
μ
A maximum)
and excellent power supply ripple rejection (PSRR
75dB at 100Hz) in battery powered applications, such
as handsets and PDAs and in noise sensitive applica-
tions, such as RF electronics.
The AP2202 also features 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-battery pro-
tection.
The output capacitor of 1.0
μ
F minimum and 2.2
μ
F
minimum near its pin are recommended when C
BYP
is
unused and 470pF respectively. Tantalum or alumin-
ium 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 concern and rapid
turn-on is necessary, omit C
BYP
and leave BYP open.
The AP2202 has adjustable, 2.5V, 2.6V, 2.7V, 2.8V,
2.9V, 3.0V, 3.3V and 4.0V versions.
The AP2202 is available in space saving SOT-23-5
package.
