# TPS76801QDR

**Texas Instruments** · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOIC-8

TPS76801QDR from Texas Instruments, in a SOIC-8. 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 | GND | power_in | Regulator ground pin for the SOIC-8 (D) package. |
| 2 | EN | input | Enable input: applying a TTL high signal shuts the regulator down, with the datasheet specifying a high-level enable input voltage of 1.7 V and a low-level enable input voltage of 0.9 V. |
| 3 | IN | power_in | Input voltage pin; the recommended input voltage range is 2.7 V to 10 V. |
| 4 | IN | power_in | Input voltage pin (second input pin, bonded in parallel with pin 3); the recommended input voltage range is 2.7 V to 10 V. |
| 5 | OUT | power_out | Regulated output voltage pin; the output current is specified from 0 to 1.0 A. |
| 6 | OUT | power_out | Regulated output voltage pin (second output pin, bonded in parallel with pin 5); the output current is specified from 0 to 1.0 A. |
| 7 | FB/NC | input | Feedback input voltage for the adjustable TPS76801 (set output 1.2 V to 5.5 V via external divider); no connect for fixed-output options. |
| 8 | PG | output | Open-drain power-good output that goes low when the output falls to between 92% and 98% of nominal; it requires an external pullup resistor and has an absolute maximum voltage of 16.5 V. |
