REG113NA-3.3 from Texas Instruments, in a SOT-23-5. 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 | VIN | power_in | Supply input voltage with operating range 1.8V to 10V for normal regulation operation. |
| 2 | GND | power_in | Ground reference. |
| 3 | Enable | input | Digital enable input, active high, TTL/CMOS compatible; output enabled when voltage ≥ 1.8V, disabled when voltage ≤ 0.5V. |
| 4 | NR | output | Noise reduction output connected to internal reference voltage; connect 0.01µF capacitor to ground to form low-pass filter for noise reduction. |
| 5 | VOUT | output | Regulated 3.3V output voltage with ±1.5% maximum accuracy, capable of 500mA peak output current. |
