REG113NA-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 voltage, operating range 1.8V to 10V with specified input voltage range VOUT + 0.4V to 10V at TJ = 25°C or VOUT + 0.6V to 10V over temperature. |
| 2 | GND | power_in | Ground connection with typical ground pin current of 850µA at IOUT = 400mA and 0.01µA to 0.2µA when disabled. |
| 3 | Enable | input | Active high enable input compatible with TTL-CMOS levels, HIGH state requires 1.8V to VIN for output enabled, LOW state requires -0.2V to 0.5V for output disabled, with input current 1nA to 100nA. |
| 4 | NR | output | Noise reduction pin with voltage range -0.3V to 6.0V; optional capacitor connection from NR to ground forms low-pass filter for internal reference voltage to reduce output noise. |
| 5 | VOUT | power_out | Regulated output voltage, fixed output version (3.0V for REG113NA-3) with accuracy ±1.5% max, output current up to 500mA peak typical, and output capacitor not required for stability. |
