BCD Semiconductor Manufacturing Limited
General Description
The AP2203 is a 150mA ULDO regulator, which pro-
vides ultra low dropout voltage (typically 165mV at
150mA), very low quiescent current (1
μ
A maximum)
in shutdown mode and excellent power supply ripple
rejection (PSRR 75dB at 100Hz) in battery powered
applications, such as handsets and PDAs and in noise
sensitive applications, such as RF electronics.
The AP2203 also features an undervoltage monitor
with an error flag output, logic compatible enable/shut-
down 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 AP2203 has 2.5V, 3.0V and 3.3V versions.
The AP2203 is available in space saving 5-pin SOT-
23-5 package.
