LM34902 - 300mA Current Limited Power Switch

Description

The LM34902 is a 0.3A PFET switch used to control the input voltage of electronic devices.

It is easily integrated into system designs that have a 2.8V to 5.3V voltage rail.

Besides the 0.45Ω PFET switch, the LM34902 can be enabled or disabled by a logic signal.
