Texas Instruments · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-5
REG102NA-5 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 | Unregulated supply input with absolute maximum rating of -0.3 V to 12 V and specified operating input range of 1.8 V to 10 V. |
| 2 | GND | power_in | Ground reference pin for the regulator; typical ground pin current is 600 µA at IOUT = 250 mA. |
| 3 | Enable | input | Enable input that turns the output on when VENABLE is at least 1.8 V and off when VENABLE is 0.5 V or lower, with absolute maximum VEN of -0.3 V to VIN. |
| 4 | NR/Adjust | passive | For the fixed-voltage REG102NA-5 this is the noise reduction (NR) capacitor pin, with typical CNR of 0.01 µF and NR pin voltage limited to -0.3 V to 6.0 V. |
| 5 | VOUT | power_out | Regulated 5.0 V output for the REG102-5 version, with current limit between 340 mA and 470 mA. |
