+title: NXP PF0900 Power Management Integrated Circuit regulators
+
+maintainers:
+ - Joy Zou <joy.zou@nxp.com>
+
+description:
+ The PF0900 is a power management integrated circuit (PMIC) optimized
+ for high performance i.MX9x based applications. It features five high
+ efficiency buck converters, three linear and one vaon regulators. It
+ provides low quiescent current in Standby and low power off Modes.
