BCD Semiconductor Manufacturing Limited
HIGH SPEED, EXTREMELY LOW NOISE LDO REGULATOR AP2121
General Description
The AP2121 series are positive voltage regulator ICs
fabricated by CMOS process. Each of these ICs con-
sists of a voltage reference, an error amplifier, a resis-
tor network for setting output voltage, a current limit
circuit for current protection and a chip enable circuit
(5-pin products only).
The AP2121 series feature high ripple rejection, low
dropout voltage, low noise, high output voltage accu-
racy, and low current consumption which make them
ideal for use in various battery-powered devices.
The AP2121 series have 1.5V, 1.8V, 2.5V, 2.8V, 3.0V,
3.2V and 3.3V versions.
The AP2121 are available in standard SOT-23-3 and
SOT-23-5 packages.
