# TPS7A3001DRBR

**Texas Instruments** · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SON-8-EP(3x3)

TPS7A3001DRBR from Texas Instruments, in a SON-8-EP(3x3). 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 | OUT | power_out | Regulated negative output voltage (-1.18 V to -33 V); requires ≥ 2.2 µF load capacitor to GND for stability. |
| 2 | FB | input | Feedback input that sets the output voltage of the regulator. |
| 3 | NC | unconnected | Not internally connected; must be left open or tied to GND. |
| 4 | GND | power_in | Ground reference. |
| 5 | EN | input | CMOS logic-level compatible enable input; regulator enabled/disabled by voltage threshold; can be connected to IN if unused. |
| 6 | NR/SS | passive | External capacitor connection for noise reduction and soft-start control. |
| 7 | DNC | unconnected | Do not connect; must not be routed to any electrical net including GND or IN. |
| 8 | IN | power_in | Negative input supply voltage range -3 V to -35 V. |
| 9 | PowerPAD | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
