Broad ecosystem and support from Microchip

Packaging

Type: S-PAK-5 surface-mount power package, also known as TO-263-5 or D2PAK-5

Material: Molded epoxy body, copper leadframe, tin-plated leads

Size: Compact power package footprint; consult datasheet for exact dimensions (typical TO-263 body ~10 x 9.5 mm, height ~4.5 mm)

Pin configuration: 5 leads commonly assigned to VIN, VOUT, GND, EN, and ADJ/Bypass depending on version

Thermal characteristics: Large thermal tab for heat spreading; designed for high current with good junction-to-case thermal performance; verify tab electrical connection in the datasheet

Electrical properties: Low dropout operation, high output current capability, stable with ceramic caps; see datasheet for voltage range, accuracy, PSRR, noise, and limits

Lifecycle

Status: Generally active and supported within Microchip’s portfolio. Always verify current lifecycle on our website
