LM321S5 from TECH PUBLIC, 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 | +IN | input | Non-inverting input; common-mode range is 0 to Vcc-1.5V (absolute max -0.3V to Vcc). |
| 2 | -Vs | power_in | Negative supply (ground in single-supply use); split supplies are allowed with 3V to 36V total difference, absolute max ±20V. |
| 3 | -IN | input | Inverting input; common-mode range is 0 to Vcc-1.5V and differential input voltage is limited to ±20V. |
| 4 | OUT | output | Amplifier output with swing of 0V to Vcc-1.5V and short-circuit protection (continuous short-circuit duration). |
| 5 | +Vs | power_in | Positive supply, operating range 3V to 36V (absolute max 40V single supply). |
