Texas Instruments · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-5
REG101NA-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 | Supply input, specified over 1.8V to 10V with VIN at least VOUT + 0.4V for regulation and an absolute maximum of 12V. |
| 2 | GND | power_in | Ground reference pin for the regulator. |
| 3 | Enable | input | Output is enabled when VENABLE is at least 1.8V (up to VIN) and disabled when VENABLE is 0.5V or below, with an absolute maximum range of -0.3V to VIN. |
| 4 | NR/Adjust | passive | On the REG101-A this is the voltage-setting resistor pin; on all other models it is the noise-reduction capacitor pin (CNR = 0.01µF in the test conditions), with an absolute maximum of 6.0V. |
| 5 | VOUT | power_out | Regulated output, which requires no output capacitor for stability; the REG101-5 version regulates to 5.0V. |
