DESCRIPTION

Regulator start-up is sequenced by connecting outputs to enable pins in the desired order. A master power-on pin is provided to initiate pin-strapped power-on sequences. A status pin is available to indicate regulator undervoltages. If an overtemperature or low supply fault is detected all regulators are disabled during the fault condition. The device is available in a 40-lead 6mm × 6mm QFN with wettable flanks for optical inspection. All registered trademarks and trademarks are the property of their respective owners.
