LT3065EMSE#PBF

Analog Devices · Linear Voltage Regulators (LDO) · MSOP-12-EP

LT3065EMSE#PBF from Analog Devices, in a MSOP-12-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 IN power_in Input supply pin that withstands reverse voltage on IN relative to GND and OUT without reverse current flow, and a local bypass capacitor of 1µF to 10µF generally suffices.
2 IN power_in Input supply pin that withstands reverse voltage on IN relative to GND and OUT without reverse current flow, and a local bypass capacitor of 1µF to 10µF generally suffices.
3 SHDN input Pulling SHDN low puts the device into a low-power state and turns the output off, the pin must be driven by logic or an open collector/drain with a pull-up resistor, and it must be connected to IN if unused because the device does not function if SHDN is left unconnected.
4 PWRGD output Open-drain power-good output that actively pulls low when the output is below 90% of its nominal value, can sink 50µA, and requires an external pull-up resistor because there is no internal pull-up.
5 IMAX passive Precision current-limit programming pin where a resistor connected between IMAX and GND sets the current limit, a 22nF decoupling capacitor to ground is required, and it must be tied to GND if not used.
6 NC unconnected No connection to internal circuitry on the MSE package, and the pin may be floated or connected to GND.
7 NC unconnected No connection to internal circuitry on the MSE package, and the pin may be floated or connected to GND.
8 REF/BYP passive Capacitor from this pin to GND bypasses the reference noise and soft-starts the output (a 10nF capacitor reduces output noise to 25µVRMS over 10Hz to 100kHz), the pin must be left floating if low noise or soft-start is not required, and it must not be driven with any active circuitry.
9 GND power_in Ground for the adjustable LT3065, to which the bottom of the output-setting resistor divider should be connected directly for optimum load regulation, and which must be soldered to the PCB ground and tied to the exposed pad.
10 ADJ input Error-amplifier inverting input that regulates to 600mV referenced to GND with a typical 16nA bias current flowing out of the pin, and it should not be used for any other purpose.
11 OUT power_out Output pin that supplies power to the load and requires a minimum 3.3µF ceramic capacitor with ESR below 1Ω (4.7µF for outputs below 1.2V), with a permissible output voltage range of 600mV to 40V.
12 OUT power_out Output pin that supplies power to the load and requires a minimum 3.3µF ceramic capacitor with ESR below 1Ω (4.7µF for outputs below 1.2V), with a permissible output voltage range of 600mV to 40V.
13 GND power_in Exposed pad that is the electrical and thermal ground connection and must be soldered to the PCB ground for proper electrical and thermal performance.
