Texas Instruments · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SC-70-5
TPS71745QDCKRQ1 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, with an operating input range of 2.5 V to 6.5 V; a 0.1-μF to 1-μF capacitor is recommended for better performance. |
| 2 | GND | power_in | Ground reference pin for the regulator. |
| 3 | EN | input | Driving EN above VEN(high) turns on the regulator, and driving it below VEN(low) puts the regulator into standby mode, disabling the output and reducing operating current. |
| 4 | NR | passive | Fixed-voltage versions only: an external capacitor on this pin bypasses noise generated by the internal band gap, lowering output noise. |
| 5 | OUT | output | Regulated output voltage; a minimum capacitance of 1 μF is required for stability from this pin to ground. |
