Data Sheet
AP2132A
General Description
The AP2132A 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 AP2132A have features of large current, low
dropout voltage, high output voltage accuracy and
low input voltage. The AP2132A provide a power
good (PG) signal to indicate if the voltage level of
VOUT reaches 92% of its rating value. And it operates
with a VIN as low as 1.4V and VCTRL voltage 5V with
output voltage programmable as low as 0.6V.
The AP2132A 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 AP2132A series are available in PSOP-8
package.

Adjust output: when connected to ground, the output voltage is set by internal
resistors; when external feedback resistors are connected, the output voltage
will be VOUT=0.6V×(R1+R2)/R2
