MCP1501-20E

Microchip Tech · Voltage Reference · SOIC-8

MCP1501-20E from Microchip Tech, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 OUT output Buffered V_REF output. Sources/sinks up to 20 mA (30 mA absolute max). Nominal 2.048V for the MCP1501-20 variant. In the SOT-23 package the internal feedback connection is made on-die; the output driver is tristated in shutdown.
2 GND power_in System ground / power supply return. Must be tied to system ground.
3 GND power_in System ground / power supply return. Must be tied to system ground.
4 SHDN input Active-low shutdown digital input. Drive low to place the device in shutdown (output tristated). Device must be fully powered up before SHDN is asserted. Drive high (up to V_DD) for normal operation.
5 GND power_in System ground / power supply return. Must be tied to system ground.
6 VDD power_in Power supply input, 2.25V to 5.5V for the MCP1501-20 variant (absolute max 5.5V). Recommend a 0.1 µF decoupling capacitor placed very close to this pin. Also serves as the internal reference input rail.

CAD (KiCad official)

  • Symbol: MCP1501-20E
  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SOIC-8 (KiCad packages3D, STEP)
  • 3D model files: mcp1501-20e-etched.step / mcp1501-20e-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); mcp1501-20e.step / mcp1501-20e.glb are the bare package body.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: Microchip Tech datasheet (39 pp, sha256 f13d94a440c9f052, retrieved 2026-08-17, tier: lcsc)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
