TPS76918QDBVRQ1 from Texas Instruments, in a SOT-23-5. 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 | IN | power_in | Input pin for this older-chip device, rated 2.7 V to 10 V recommended (13.5 V absolute maximum), with a 1 µF input capacitor placed as close as possible to the IN and GND pins. |
| 2 | GND | power_in | Ground pin; all device voltages are referenced to GND. |
| 3 | EN | input | Active-low enable: driving EN low enables the output and driving it high disables the device, using the low and high enable thresholds given in the Electrical Characteristics table. |
| 4 | FB/NC | unconnected | On the fixed-output older-chip version this pin is a no-connect and must be left unconnected; on the adjustable TPS76901-Q1 it is the feedback pin and must not be left floating. |
| 5 | OUT | power_out | Regulated output pin; for the older chip a capacitor of at least 4.7 µF with ESR between 0.2 Ω and 10 Ω must be connected between OUT and GND, placed as close as possible to the pins. |
