AP2132MP-1.2G1

Manufacturer Part Number
AP2132MP-1.2G1
Description
2A CMOS LDO Regulator
Manufacturer
BCDSEMI [BCD Semiconductor Manufacturing Limited]
Datasheet
General Description
The AP2132 series are positive voltage regulator ICs
fabricated by CMOS process. The ICs consist of a
voltage reference, an error amplifier, a power
transistor, a resistor network for setting output
voltage, a current limit circuit for current protection,
and a chip enable circuit.
The AP2132 have features of large current, low
dropout voltage, high output voltage accuracy, and
low input voltage. The AP2132 provide a power good
(PG) signal to indicate if the voltage level of V
reaches 92% of its rating value. And it operates with
a V
voltage programmable as low as 0.6V.
The AP2132 are available in 1.2V, 1.5V, 1.8V, 2.5V
fixed output voltage versions and adjustable output
voltage version. The fixed versions integrate the
adjust resistors. It is also available in an adjustable
version, which can set the output voltage with
external resistor. If the pin of adjustable output
voltage is to ground, it will switch to fixed output
voltage.
The AP2132 series are available in PSOP-8 package.
