Microchip Technology MIC94080
The MIC94080 and MIC94081 feature rapid turn on. The MIC94082 and MIC94083 provide a slew rate controlled soft-start turn-on of 800 μs, while the MIC94084 and MIC94085 provide a slew rate controlled soft-start turn-on of 120 μs. The soft-start feature is provided to prevent an in-rush current event from pulling down the input supply voltage.FEATURES
