AP7350
150mA ULTRA-LOW QUIESCENT CURRENT LDO with ENABLE
Description Pad Assignments
The AP7350 is a low dropout regulator with high output voltage
accuracy. The AP7350 includes a voltage reference, error amplifier,
current limit circuit and an enable input to turn it on/off. With the WL-CSP
integrated resistor network, fixed output voltage versions can be

The AP7350 is available in the wafer level chip scale WLB0606-4
package. This part is one of the smallest LDO footprints in the
industry allowing for the use of a bare minimum of board space within
the application.
