LP3965EMPX-ADJ
Texas Instruments · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-223-5
LP3965EMPX-ADJ from Texas Instruments, in a SOT-223-5. 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 | SD | input | Shutdown input: pulling it low (VSD ≤ 0.2V) turns the output off and cuts ground pin current to about 15µA, and it must be pulled high through a 10kΩ resistor when used; survival range is −0.3V to VIN+0.3V. |
| 2 | VIN | power_in | Input supply, specified from 2.5V to 7.0V operating, with a survival limit of −0.3V to +7.5V. |
| 3 | VOUT | power_out | Regulated output, with an output voltage survival limit of −0.3V to +7.5V; the internal output PMOS diode to VIN can carry about 200mA DC and 1A peak when forward biased. |
| 4 | SENSE/ADJ | input | Output adjust pin for the ADJ version (reference about 1.2V) or remote sense pin for regulation at the load; the SENSE voltage must not exceed VOUT+0.3V. |
| 5 | GND | power_in | Ground reference pin; ground pin current is typically 5mA at a 1.5A load. |

LP3965EMPX-ADJ - Footprint:
Package_TO_SOT_SMD:SOT-223-5 - 3D model: SOT-223-5, generated from the KiCad footprint (body from the F.Fab outline, terminals on the pads, 1.45 mm nominal SOT height). Neither the vendor nor KiCad ships a 3D model for this package, so the dimensions are nominal, not the manufacturer's CAD (STEP)
