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. |
