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). |
