# TPS22917DBVR

**Texas Instruments** · AC-DC Controllers and Regulators · SOT-23-6

TPS22917DBVR from Texas Instruments, in a SOT-23-6. 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 | VIN | power_in | Switch input supply, 1 V to 5.5 V (absolute max 6 V). Source terminal of the internal P-channel MOSFET; connect a bypass capacitor (CIN) close to this pin. |
| 2 | GND | power_in | Device ground reference. |
| 3 | ON | input | Active-high switch control input (VIH ≥ 1 V, VIL ≤ 0.35 V). Do not leave floating. On the TPS22917L variant this pin is active-low. Absolute max 6 V. |
| 4 | CT | passive | Switch slew-rate / turn-on time control. Connect a capacitor from CT to VIN to increase output slew rate and turn-on time (5 V tON ≈ 100 µs at CT open, ≈ 4000 µs at CT = 1000 pF). Can be left floating for the fastest timing. Rated to 7 V. |
| 5 | QOD | passive | Quick Output Discharge pin. Enable by (a) placing an external resistor between VOUT and QOD, (b) tying QOD directly to VOUT to use the internal ~150 Ω discharge resistance, or (c) leaving QOD floating to disable output discharge. Rated 0 V to 5.5 V. |
| 6 | VOUT | power_out | Switch output (drain of internal P-channel MOSFET). Rated 0 V to 5.5 V, up to 2 A continuous switch current. |
