# TPS73730DRBR

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

TPS73730DRBR from Texas Instruments, in a VSON-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 | output | Regulated regulator output requiring ≥1.0μF external capacitor for stability. |
| 2 | N/C | unconnected | No internal connection. |
| 3 | NR | passive | Noise reduction pin with internal 27kΩ series resistor for RC low-pass filtering of output noise in fixed-voltage versions. |
| 4 | GND | power_in | Ground connection with exposed thermal pad. |
| 5 | EN | input | Enable input requiring ≥1.7V to enable operation and ≤0.5V to enter shutdown mode; cannot be left floating. |
| 6 | N/C | unconnected | No internal connection. |
| 7 | N/C | unconnected | No internal connection. |
| 8 | IN | power_in | Unregulated input power supply requiring 2.2V to 5.5V operating voltage. |
| 9 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |

## CAD (KiCad official)

- Symbol: `TPS73730DRBR`
- Footprint: `Package_SON:VSON-8-1EP_3x3mm_P0.65mm_EP1.6x2.4mm`
- 3D model: VSON-8-EP(3x3), generated from the KiCad footprint (body from the F.Fab outline, terminals on the pads, 0.9 mm nominal VQFN 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: `tps73730drbr-etched.step` / `tps73730drbr-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `tps73730drbr.step` / `tps73730drbr.glb` are the bare package body.
