# TPS71719DCKR

**Texas Instruments** · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SC-70-5

TPS71719DCKR from Texas Instruments, in a SC-70-5. 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 | IN | input | Input to the device; a 0.1-μF to 1-μF capacitor is recommended for better performance. |
| 2 | GND | power_in | Ground reference for the device. |
| 3 | EN | input | Enable pin; driving above VEN(high) turns on the regulator, driving below VEN(low) disables the output and puts the regulator into standby mode. |
| 4 | NR | passive | Noise reduction pin for fixed voltage versions; the noise reduction capacitor filters noise generated by the internal band gap to lower output noise. |
| 5 | OUT | output | Regulated output voltage; a minimum capacitance of 1 μF to ground is required for stability. |
