LT1965EMS8E-3.3#TRPBF

Analog Devices · Linear Voltage Regulators (LDO) · MSOP-8-EP

LT1965EMS8E-3.3#TRPBF from Analog Devices, in a MSOP-8-EP. 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 pin that supplies power to the load and needs a minimum 10µF output capacitor to prevent oscillations.
2 OUT power_out Output pin that supplies power to the load and needs a minimum 10µF output capacitor to prevent oscillations.
3 SENSE/ADJ input On the fixed 3.3V version this is SENSE, the error amplifier input that should connect to OUT for optimum regulation, with a bias current of 100µA at the nominal output voltage.
4 GND power_in Ground pin that should be tied directly to pin 5, pin 9 and the PCB ground.
5 GND power_in Ground pin that should be tied directly to pin 4, pin 9 and the PCB ground.
6 SHDN input Shutdown pin that turns the output off when pulled low, with SHDN pin current typically less than 5.5µA, and should connect to IN if unused.
7 IN power_in Input pin that supplies power to the device and should have a 1µF to 10µF bypass capacitor if more than six inches from the main input filter capacitor.
8 IN power_in Input pin that supplies power to the device and should have a 1µF to 10µF bypass capacitor if more than six inches from the main input filter capacitor.
9 EP (GND) power_in Exposed pad that must be tied directly to pins 4 and 5 and the PCB ground to provide enhanced thermal performance.
