Microchip Tech · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-5
MCP1711T-25I from Microchip Tech, in a SOT-23-5. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VIN | power_in | Unregulated input supply; the datasheet gives an input voltage range of 1.4 V to 6.0 V, and a 0.1 µF capacitor is sufficient for stability in most applications. |
| 2 | GND | power_in | Regulator ground that the LDO output is referenced to; only the LDO bias current flows through this pin, and the GND trace to the load ground should be kept as short as possible. |
| 3 | SHDN | input | Active-high shutdown input that enables the output at a logic high of at least 0.91 V and disables it at a logic low of at most 0.38 V; the output becomes unstable if this pin is left floating. |
| 4 | NC | unconnected | Not connected internally; the datasheet says this pin should be left floating or connected to the ground plane. |
| 5 | VOUT | power_out | Regulated output of 2.5 V nominal for this -25 variant (2.4750 V to 2.5250 V), with a maximum output current of 150 mA; the positive terminal of the output capacitor should be placed as close to this pin as possible. |
