The APE8838 is a highly accurate, dual, low noise, CMOS LDO voltage
regulators with enable function. The output voltage for each regulator is set
independently by fuse trimming. As illustrated in function block diagram, it consists of a
reference, error amplifier, a P-channel pass transistor, an ON/OFF control logic and an
internal feedback voltage divider. The band gap reference is connected to the error
amplifier, which compares the reference with the feedback voltage and amplifies the
voltage difference. If the feedback voltage is lower than the reference voltage, the
pass- transistor gate is pulled lower, which allows more current to pass to the VOUT pin
and increases the output voltage. If the feedback voltage is too high, the pass
transistor gate is pulled up to decrease the output voltage. The output voltage is feed
back through an internal resistive divider connected to VOUT pin. Additional blocks
include an output current limiter, thermal sensor, and shutdown logic.
