TLV1821LDBVR from Texas Instruments, in a SOT-23-5. 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 | tri_state | Open-drain comparator output pin that sinks current to V- when active; external pull-up resistor to 40V maximum is required. |
| 2 | V+ | power_in | Positive supply voltage pin, operating range 2.4V to 40V above V-. |
| 3 | IN+ | input | Non-inverting input pin, accepts signals in range V- - 0.2V to V+ + 0.2V. |
| 4 | IN- | input | Inverting input pin, accepts signals in range V- - 0.2V to V+ + 0.2V. |
| 5 | V- | power_in | Negative supply voltage reference pin, establishes lower rail for 2.4V to 40V supply range with V+. |
