General Description

The AP2202 is a 150mA ULDO regulator which pro-

vides very low noise (45µVrms at 80Hz-100KHz),

ultra low dropout voltage (typically 165mV at

150mA), very low quiescent current (1µA 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 1.0µF minimum and 2.2µF

minimum near its pin are recommended when CBYP 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 CBYP 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.
