Positive Linear Regulator Output. GH is the output of the positive linear regulator. GH

can supply as much as 20mA to the load. Bypass GH to GND with a 1μF or greater,

low-ESR, ceramic capacitor.

Positive Linear Regulator Input. IN3 is the input to the positive linear regulator. Drive

IN3 with a doubling, tripling, or quadrupling charge pump from SW. IN3 voltage can go

as high as 38V.

Power Ground. PGND is the source of the internal 250mΩ N-Channel MOSFET

switch. Connect PGND to GND as close to the MP1530 as possible.

No internal electrical connections. Solder it to the lowest potential (IN2 pin) plane

to reduce thermal resistance.
