# TPS77350DGK

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

TPS77350DGK from Texas Instruments, in a VSSOP-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 | FB/SENSE | input | On the fixed-output TPS77350 this SENSE pin must be connected to the regulator output as short as possible, and RC filtering between SENSE and OUT is not recommended because it may cause oscillation. |
| 2 | RESET | output | Open-drain, active-low reset output that goes high-impedance after a 220-ms delay once OUT reaches 95% of its regulated voltage, goes low-impedance when OUT falls below 95%, and requires a pullup resistor. |
| 3 | EN | input | Enable input where a logic low enables the regulator and a logic high puts the device into shutdown mode. |
| 4 | GND | power_in | Regulator ground, which the output capacitor (minimum 1 µF with qualifying ESR, or at least 10 µF) must be connected to between OUT and GND. |
| 5 | IN | input | Regulator input voltage terminal; the datasheet lists IN on pins 5 and 6. |
| 6 | IN | input | Regulator input voltage terminal; the datasheet lists IN on pins 5 and 6. |
| 7 | OUT | output | Regulated output voltage terminal; the datasheet lists OUT on pins 7 and 8 and requires an output capacitor from OUT to GND for loop stability. |
| 8 | OUT | output | Regulated output voltage terminal; the datasheet lists OUT on pins 7 and 8 and requires an output capacitor from OUT to GND for loop stability. |
