TPS74633PQWDRVRQ1

Texas Instruments · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · WSON-6-EP(2x2)

TPS74633PQWDRVRQ1 from Texas Instruments, in a WSON-6-EP(2x2). Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 OUT power_out Regulated output voltage pin; capacitor of 0.47µF minimum is required from OUT to ground for stability; use ceramic X5R or X7R type for best transient response; place output capacitor close to the output of the device.
2 NC unconnected No internal connection; ground this pin for better thermal performance.
3 GND power_in Ground pin; electrically connected to the thermal pad.
4 EN input Enable input pin; drive EN greater than VEN(HI)=1.0V to turn on the regulator; drive EN less than VEN(LO)=0.3V to put the LDO into shutdown mode.
5 PG output Power-good output pin available in open-drain and push-pull topologies; pullup resistor required for open-drain version; ground or leave floating if not used for open-drain; leave floating if not used for push-pull.
6 IN power_in Input supply pin accepting 1.5V to 6.0V; use 1µF or larger ceramic capacitor from IN to ground for best transient response and to minimize input impedance; place input capacitor close to the output of the device.
7 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
