Microchip Tech · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-5
MCP1711T-33I 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 voltage, specified from 1.4V to 6.0V, and low source impedance (about 0.1 µF of capacitance for most applications) is needed for stable LDO operation. |
| 2 | GND | power_in | Regulator ground terminal, tied to the negative side of the input and output capacitors, with voltage drops minimized between this pin and the load ground. |
| 3 | SHDN | input | Shutdown input that enables the output when at logic High and disables it when pulled to logic Low; the output voltage becomes unstable if this pin is left floating. |
| 4 | NC | unconnected | Not connected on the SOT-23 package; it may be left floating or tied to the ground plane. |
| 5 | VOUT | power_out | Regulated voltage output that supplies the DC load current, with a maximum output current rating of 150 mA. |
