LT3090IDD#PBF

Analog Devices · Linear Voltage Regulators (LDO) · TDFN-10-EP(3x3)

LT3090IDD#PBF from Analog Devices, in a TDFN-10-EP(3x3). 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 power_in IN supplies power to the regulator and requires a bypass capacitor of 2.2µF to 4.7µF, with all IN pins tied together and to the exposed pad.
2 IN power_in IN supplies power to the regulator and must be tied together with all other IN pins and the exposed backside pad on the PCB.
3 ILIM passive ILIM programs the current limit through an external resistor to IN, its voltage must not be driven more than 0.3V below IN, and it should be tied to IN if unused.
4 IMONP output IMONP sources current equal to 1/2000 of output current through a resistor to GND for positive current monitoring, must be at least 2V below IMONN, and should be tied to IN if unused.
5 IMONN output IMONN sinks current equal to 1/1000 of output current through a resistor to GND for negative current monitoring, must be at least 2V above IN and IMONP, and should be tied to GND if unused.
6 SHDN input SHDN is a bidirectional shutdown pin with threshold references to GND, turning the output off within ±0.45V of GND and on beyond ±1.4V, and must not be floated.
7 SET input SET is the inverting error amplifier input where a precision 50µA current flows, a resistor to GND programs the output voltage, and it must not be driven more than 0.3V below IN.
8 GND power_in GND supplies the quiescent current and NPN pass transistor drive current and must not be driven more than 0.3V below IN during normal operation or a fault condition.
9 OUT power_out OUT supplies power to the load and requires a minimum 4.7µF output capacitor with ESR below 0.5Ω and a minimum 10µA load current to prevent oscillation.
10 OUT power_out OUT supplies power to the load and all OUT pins should be tied together for best performance.
11 IN power_in The exposed backside pad is an electrical and thermal connection to IN and the device substrate and must be soldered to the PCB.
