MCP1703T-5002E from Microchip, in a SOT-23A-3. 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 | GND | power_in | Regulator ground / negative reference. LDO output regulation is referenced to this pin; only the LDO bias current (~2.0 µA typ) flows out of it. Tie directly to the negative side of the input and output capacitors and the load return. |
| 2 | VOUT | power_out | Regulated 5.0 V output (VR = 5.0 V for the 5002 option). Delivers up to 250 mA continuous with 1 µF (min) ceramic output capacitor; DC load current flows out of this pin. Tolerance ±0.4% typical at 25 °C, ±3% max over temperature. |
| 3 | VIN | power_in | Unregulated supply input, 2.7 V to 16 V operating (18 V absolute max). For the 5 V output variant VIN must exceed VOUT + dropout (typ 330 mV / max 650 mV at 250 mA). A low-ESR 1 µF ceramic bypass capacitor close to the pin is recommended for stability. |
