TPS7A3701DRVR 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 | output | Regulator output. Supplies up to 1 A at VFB to 5.5 V (V_DO). Requires a 1.0-uF or larger ceramic capacitor of any type for stability. |
| 2 | FB | input | Feedback input to the internal error amplifier for the adjustable-voltage TPS7A3701. Connect the external resistor divider from OUT to FB to GND to set VOUT. Internal reference VFB = 1.204 V typ; nominal R1 = VOUT(nom) x 15.833 kohm. |
| 3 | GND | power_in | Device ground return. Must be tied together with the exposed PowerPAD on the package bottom for proper operation and thermal performance. |
| 4 | EN | input | Active-high enable. Driving EN high (>=1.7 V, up to VIN) turns the regulator on; driving it low (<=0.5 V) puts the device into shutdown (I_SHDN ~20 nA typ). EN must not be left floating; tie to IN if unused. Absolute-max range -0.3 to 6 V. |
| 5 | N/C | unconnected | No internal connection. Leave floating or tie to GND for best PCB layout; do not use as an electrical tie point. |
| 6 | IN | power_in | Unregulated input supply, 2.2 V to 5.5 V recommended (abs-max 6 V). Bypass to GND with a 1-uF (or larger) ceramic capacitor placed close to the pin. |
| PAD | PowerPAD | power_in | Exposed thermal pad on the package underside. Must be soldered to the PCB ground plane; electrically tied to GND (pin 3) internally and is the primary heat-dissipation path. |
