# TPS7A1601ADGNR

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

TPS7A1601ADGNR from Texas Instruments, in a HVSSOP-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 | OUT | power_out | Regulator output pin; a capacitor greater than 2.2 µF must be tied from this pin to ground for stability, and a 10-µF ceramic capacitor is recommended as close to the device as possible. |
| 2 | FB/DNC | input | For the adjustable version this is the feedback input to the control-loop error amplifier that sets the output voltage through external resistors; do not route this pin to any net, including GND or IN, on fixed-voltage versions. |
| 3 | PG | output | Open-collector, active-high power-good output with a user-programmable delay; leave open or connect to GND if the power-good function is not needed. |
| 4 | GND | power_in | Ground pin. |
| 5 | EN | input | Enable pin that turns the regulator on when VEN is at or above VEN_HI and off when VEN is at or below VEN_LO; it may be tied to IN if unused, and VEN must remain at or below VIN at all times. |
| 6 | NC | unconnected | No internal connection; this pin can be left open or tied to any voltage between GND and IN. |
| 7 | DELAY | output | Delay pin for the PG delay time; connect a capacitor to GND to set the delay, or leave open if the reset function is not needed, with DELAY pin voltage specified from 0 V to 5 V. |
| 8 | IN | power_in | Regulator input supply pin, operating from 3 V to 60 V; a capacitor greater than 0.1 µF must be tied from this pin to ground for stability, and a 10-µF ceramic capacitor is recommended close to the device. |
| 9 | Thermal pad | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |

## CAD (KiCad official)

- Symbol: `TPS7A1601ADGNR`
- Footprint: `Package_SO:HVSSOP-8-1EP_3x3mm_P0.65mm_EP1.57x1.89mm`
- 3D model: HVSSOP-8, generated from the KiCad footprint (body from the F.Fab outline, terminals on the pads, 1.0 mm nominal HVSSOP height). Neither the vendor nor KiCad ships a 3D model for this package, so the dimensions are nominal, not the manufacturer's CAD (STEP)
- 3D model files: `tps7a1601adgnr-etched.step` / `tps7a1601adgnr-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `tps7a1601adgnr.step` / `tps7a1601adgnr.glb` are the bare package body.
