# TLV73311PDBVR

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

TLV73311PDBVR 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 | Input supply pin, 1.4 V to 5.5 V recommended (6.0 V abs max). A small ceramic input capacitor to GND is recommended, though the device can operate cap-free. |
| 2 | GND | power_in | Device ground reference pin. |
| 3 | EN | input | Active-high enable input. Drive EN greater than V_EN(HI) to turn on the regulator; drive EN less than V_EN(LO) to place the LDO into shutdown mode. Range 0 V to V_IN. |
| 4 | NC | unconnected | No internal connection. May be left floating or tied to any potential within abs-max ratings. |
| 5 | OUT | power_out | Regulated output voltage pin (fixed 1.1 V for TLV73311P). For best transient response, use a small 1-µF ceramic capacitor from this pin to ground; cap-free stable operation is also supported. |

## CAD (KiCad official)

- Symbol: `TLV73311PDBVR`
- Footprint: `Package_TO_SOT_SMD:SOT-23-5`
- 3D model: SOT-23-5 (KiCad packages3D, STEP)
- 3D model files: `tlv73311pdbvr-etched.step` / `tlv73311pdbvr-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `tlv73311pdbvr.step` / `tlv73311pdbvr.glb` are the bare package body.
