# TPS7A3001MDGNTEP

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

TPS7A3001MDGNTEP from Texas Instruments, in a MSOP-8-EP. 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 | output | Regulator output; capacitor ≥2.2µF to GND required for stability. |
| 2 | FB | input | Feedback input to error amplifier; controls output voltage setting. |
| 3 | NC | unconnected | Not internally connected; may be left open or tied to GND. |
| 4 | GND | power_in | Ground reference. |
| 5 | EN | input | Enable/disable input; regulator enabled when |VEN| ≥ 2.0V; constraint |VEN| ≤ |VIN|. |
| 6 | NR/SS | input | Noise reduction and soft-start control; connect external capacitor to filter bandgap noise and manage soft-start ramp. |
| 7 | DNC | unconnected | Do not connect; cannot be routed to any electrical net, not even GND or IN. |
| 8 | IN | power_in | Negative supply input; operating range -36V to -3V. |
| 9 | PowerPAD | passive | Exposed thermal pad; may be left open or soldered to GND plane for enhanced thermal performance. |
