LT3081ER#PBF

Analog Devices · Linear Voltage Regulators (LDO) · TO-263-7

LT3081ER#PBF from Analog Devices, in a TO-263-7. 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 ILIM passive A resistor between this pin and OUT programs the output current limit, typically 360mA/kΩ with a 450Ω offset, and the device keeps an internal current limit if the pin is left open.
2 SET input This is the error amplifier's noninverting input, with a fixed 50µA current source flowing out of it, and a single external resistor sets VOUT over the range 0V to 34.5V.
3 IMON output This pin sources a current typically equal to ILOAD/5000 (200µA per amp) and its output is valid from VOUT + 0.4V to VOUT - 40V; connect it to OUT if unused.
4 OUT power_out This is the power output of the device, which requires a 5mA minimum load current for proper regulation; the tab is internally tied to this pin and must be tied directly to OUT at the PCB.
5 TEMP output This pin delivers a current of 1µA/°C for temperatures above 5°C (typically 25µA at 25°C), valid for voltages from VOUT + 0.4V to VOUT - 40V; connect it to OUT if unused.
6 IN power_in This pin supplies power to the regulator, and its voltage must be between the dropout voltage and 36V above the OUT pin, depending on output load current.
7 NC unconnected No connect pin with no connection to internal circuitry; it may be tied to IN, OUT, GND or left floating.
8 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
