# TLV1811DBVR

**Texas Instruments** · Comparators · SOT-23-5

TLV1811DBVR 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 | OUT | output | Comparator push-pull output. Sinks and sources milliamps of current, suitable for driving an LED or a MOSFET gate capacitive load. |
| 2 | V- | power_in | Negative supply voltage (typically GND in single-supply operation). Supply range from 0V to 40V referenced to V+. |
| 3 | IN+ | input | Non-inverting comparator input. Rail-to-rail input range; low input bias current of 150fA typical. |
| 4 | IN- | input | Inverting comparator input. Rail-to-rail input range; low input bias current of 150fA typical. |
| 5 | V+ | power_in | Positive supply voltage. 2.4V to 40V range with respect to V-. 500µV typical input offset over full supply range. |

## CAD (KiCad official)

- Symbol: `TLV1811DBVR`
- Footprint: `Package_TO_SOT_SMD:SOT-23-5`
- 3D model: SOT-23-5 (KiCad packages3D, STEP)
- 3D model files: `tlv1811dbvr-etched.step` / `tlv1811dbvr-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `tlv1811dbvr.step` / `tlv1811dbvr.glb` are the bare package body.
