TPS74650PQWDRBRQ1

Texas Instruments · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SON-8-EP(3x3)

TPS74650PQWDRBRQ1 from Texas Instruments, in a SON-8-EP(3x3). 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 OUT power_out Regulated output voltage pin; requires capacitor to ground for stability.
2 NC unconnected No internal connection; ground this pin for improved thermal performance.
3 NC unconnected No internal connection; ground this pin for improved thermal performance.
4 GND power_in Ground pin.
5 EN input Enable input; drive greater than VEN(HI) to enable regulator or less than VEN(LO) for shutdown.
6 PG output Power-good open-drain or push-pull output for power supply sequencing.
7 NC unconnected No internal connection; ground this pin for improved thermal performance.
8 IN power_in Input power supply pin; use ceramic capacitor to ground for transient response.
9 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
