MIC94310-GYMT-TR IC REG LINEAR 1.8V 200MA 4TMLF Microchip Technology

 

General Description

The MIC94070-73 are high-side load switches designed for operation between 1.7V to 5.5V. The devices contain a low on-resistance P-channel MOSFET that supports 1.2A of continuous current. The MIC94071 and MIC94073 feature an active load discharge circuit which insures capacitive loads retain no charge when the main switch is in an OFF state.
