AP1151 Datasheet Low Noise LDO Regulator

Manufacturer: AKM (Asahi Kasei Microdevices)

General Description

The AP1151 is a low dropout linear regulator with On/Off control, which can supply 200mA load current.

The output voltage can be set between 1.3 to 13.5V by an external resistor, and the output capacitor is available to use a small 0.22uF ceramic capacitor.

The AP1151 has a built-in over-current protection and thermal shutdown protection circuit, and is possible to provide two types of package, the AP1151ADS is the SOT23-5 package and the AP1151AEU is the PLP1822-6 package with Heat Sink pad.
