REG102NA-3.3 from Texas Instruments, 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 | Supply input, with an operating input range of 1.8 V to 10 V and VIN at least VOUT + 0.4 V (VOUT + 0.6 V over temperature) for specified regulation; absolute maximum is 12 V. |
| 2 | GND | power_in | Ground reference pin; ground pin current is 600 µA typical at IOUT = 250 mA and 800 µA maximum. |
| 3 | Enable | input | Enable input: the output is enabled when VENABLE is at least 1.8 V and disabled when VENABLE is 0.5 V or less, with an absolute maximum range of -0.3 V to VIN. |
| 4 | NR/Adjust | passive | On the fixed-voltage REG102NA-3.3 this is the noise reduction pin for an optional 0.01 µF CNR capacitor, with an absolute maximum voltage of 6.0 V. |
| 5 | VOUT | power_out | Regulated output of 3.3 V for this version, with ±1.5% maximum accuracy and specified operation up to 250 mA load. |
