APE8977MP
2.5A LINEAR REGULATOR
DESCRIPTIOON
The APE8977MP is a simple, cost-effective and
high-speed linear regulator. The regulator is capable of
actively sinking or sourcing up to 2.5A while regulating
an output voltage to within 40mV. The desired output
voltage can be programmed by two external voltage
divider resistors of the REFEN pin.
The APE8977MP also incorporates a high-speed
differential amplifier to provide ultra-fast response in
line/load transient. Other features include extremely low
initial offset voltage, excellent load regulation, current
limiting in bi-directions and on-chip thermal shut-down
protection. Built-in soft-start function avoids a mis-
operation by inrush current.
The APE8977MP are available in the ESOP-8
(Exposed Pad) surface mount packages.
