# TPS7A6933QDRQ1

**Texas Instruments** · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOIC-8

TPS7A6933QDRQ1 from Texas Instruments, in a SOIC-8. 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 | VIN | power_in | Input power-supply voltage for 4 V to 40 V operation. |
| 2 | SI | input | Sense input pin to supervise input voltage via external voltage divider to VIN and GND. |
| 3 | NC | unconnected | Not-connected pin with no internal connection. |
| 4 | CT | output | Reset-pulse delay adjustment pin; connect a capacitor from this pin to GND to control the PG reset delay. |
| 5 | GND | power_in | Ground reference. |
| 6 | PG | tri_state | Power good open-drain output that must connect to VOUT via an external resistor; logic high when VOUT exceeds the power-on-reset threshold. |
| 7 | SO | tri_state | Sense output open-drain pin that must connect to VOUT via an external resistor; logic low when sense input falls below the sense-low threshold. |
| 8 | VOUT | power_out | Regulated output voltage with 150 mA output current capability and 300 mV typical dropout at 150 mA. |
