REG102NA-A 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; the operating input range is 1.8V to 10V (absolute maximum 12V), and VIN must be at least VOUT + 0.4V (VOUT + 0.6V over temperature) for specified regulation. |
| 2 | GND | power_in | Ground reference pin; typical ground pin current is 600µA at IOUT = 250mA (800µA maximum), and it drops to 0.01µA typical when the output is disabled. |
| 3 | Enable | input | Enable input: a high level of at least 1.8V turns the output on and a low level of 0.5V or less turns it off, with an absolute maximum of -0.3V to VIN. |
| 4 | NR/Adjust | passive | For the REG102-A (adjustable) version this is the voltage-setting resistor pin, with a 1.26V reference and 0.2µA typical (1µA maximum) adjust pin current, and the absolute maximum pin voltage is 6.0V. |
| 5 | VOUT | power_out | Regulated output; the adjustable version is set to 2.5V to 5.5V, and no output capacitor is required for stability. |
