# TPS76133DBVR

**Texas Instruments** · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-5

TPS76133DBVR from Texas Instruments, in a SOT-23-5. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | IN | power_in | Unregulated input voltage supply. Recommended operating range 3.68 V to 16 V for the TPS76133; absolute maximum -0.3 V to 16 V. A bypass capacitor to GND is recommended. |
| 2 | GND | power_in | Device ground reference. All voltages are referenced to this pin. |
| 3 | EN | input | Active-high enable input. Drive above 2 V to enable the regulator; drive below 0.8 V to place the device in shutdown (<1 µA standby current). Voltage range -0.3 V to VI + 0.3 V; input current typically 2.5 µA at EN = VI. |
| 4 | NC | unconnected | No internal connection. Leave floating or tie to GND. |
| 5 | OUT | power_out | Regulated 3.3-V output (3.26 V to 3.34 V typical at TJ = 25°C). Supplies up to 100 mA continuous output current with an internal current limit of 100-135 mA. Requires an output capacitor (typ. 4.7 µF) for stability. |

## CAD (KiCad official)

- Symbol: `TPS76133DBVR`
- Footprint: `Package_TO_SOT_SMD:SOT-23-5`
- 3D model: SOT-23-5 (KiCad packages3D, STEP)
- 3D model files: `tps76133dbvr-etched.step` / `tps76133dbvr-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `tps76133dbvr.step` / `tps76133dbvr.glb` are the bare package body.

## 3D model downloads

Two STEP files. Same geometry, different body top:

| File | Size | Use it when |
|---|---|---|
| [`tps76133dbvr.step`](tps76133dbvr.step) | 85 KB | You want the bare part, or you mark your own boards. |
| [`tps76133dbvr-etched.step`](tps76133dbvr-etched.step) | 2.3 MB | You want the part with `TPS76133DBVR` already on it. |

The marking in the etched file is real recessed geometry cut into the solid, not a
texture or a decal: 558 faces against 102 in the bare model. It
survives export, section views, and rendering in any CAD tool, and it drops straight
into KiCad or Fusion with no extra setup.
