# TPS7325QD

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

TPS7325QD 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 | GND | power_in | Ground reference for the regulator; all voltages are specified with respect to this terminal. |
| 2 | EN | input | Active-low enable: a logic high shuts down the regulator into sleep mode (0.5 µA max quiescent at TJ = 25°C), and the pin is rated -0.3 V to 11 V. |
| 3 | IN | power_in | Unregulated input supply, rated -0.3 V to 11 V; pins 3 and 4 are both IN. |
| 4 | IN | power_in | Unregulated input supply, rated -0.3 V to 11 V; pins 3 and 4 are both IN. |
| 5 | OUT | power_out | Regulated output (2.5 V fixed for TPS7325, 0 to 500 mA output current range); pins 5 and 6 are both OUT. |
| 6 | OUT | power_out | Regulated output (2.5 V fixed for TPS7325, 0 to 500 mA output current range); pins 5 and 6 are both OUT. |
| 7 | SENSE | input | Output-voltage sense input for the fixed-voltage TPS7325 (FB on the adjustable TPS7301), which should be tied to OUT as close to the device as possible and is rated -0.3 V to 11 V. |
| 8 | RESET | output | Open-drain NMOS active-low reset output that goes low on output undervoltage and returns high after a 200-ms (typ) delay once the condition ends. |

## CAD (KiCad official)

- Symbol: `TPS7325QD`
- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`
- 3D model: SOIC-8 (KiCad packages3D, STEP)
- 3D model files: `tps7325qd-etched.step` / `tps7325qd-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `tps7325qd.step` / `tps7325qd.glb` are the bare package body.
