LT1962EMS8-3#PBF from Analog Devices, in a MSOP-8. 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 | power_out | Output supplies power to the load, and a minimum output capacitor of 3.3µF is required to prevent oscillations. |
| 2 | SENSE | input | For the LT1962-3 fixed-voltage version, SENSE is the input to the error amplifier and should connect to OUT for optimum regulation, with a bias current of 10µA at the nominal output voltage. |
| 3 | BYP | passive | Bypass pin clamped internally to ±0.6V, where a maximum 0.01µF capacitor from OUT reduces output noise to 20µVRMS, and it must be left unconnected if not used. |
| 4 | GND | power_in | Ground reference pin. |
| 5 | SHDN | input | Shutdown pin turns the output off when pulled low, can be driven by 5V logic or open-collector logic with a pull-up resistor, and must be connected to VIN if unused. |
| 6 | NC | unconnected | No connect; not internally connected, but may be tied to the PC board for improved power handling. |
| 7 | NC | unconnected | No connect; not internally connected, but may be tied to the PC board for improved power handling. |
| 8 | IN | power_in | Input supply pin, where a bypass capacitor of 1µF to 10µF is sufficient and the device withstands reverse input voltages without reverse current flow. |
