Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | REF/BYP | passive | A single capacitor from this pin to GND bypasses reference noise and soft-starts the reference (10nF gives 30µVRMS over 10Hz to 100kHz), the pin is actively pulled low in shutdown, must be left floating if unused, must not be driven by active circuitry, and its voltage is limited to -0.3V to 1V. |
| 2 | ADJ | input | This is the inverting input of the error amplifier, which regulates ADJ to 600mV referenced to GND, with a typical bias current of 15nA flowing out of the pin. |
| 3 | OUT | power_out | This output pin supplies load power, requires a minimum 3.3µF low-ESR ceramic output capacitor to prevent oscillation, and has an output voltage range of 600mV to 19V. |
| 4 | OUT | power_out | This output pin supplies load power, requires a minimum 3.3µF low-ESR ceramic output capacitor to prevent oscillation, and has an output voltage range of 600mV to 19V. |
| 5 | IN | power_in | This input pin supplies power to the device over a 1.6V to 45V supply range, and a 1µF to 10µF bypass capacitor is required if the device is more than six inches from the input filter capacitor. |
| 6 | IN | power_in | This input pin supplies power to the device over a 1.6V to 45V supply range, and a 1µF to 10µF bypass capacitor is required if the device is more than six inches from the input filter capacitor. |
| 7 | SHDN | input | Pulling this pin low puts the device into a low-power state and turns the output off, SHDN pin current is typically under 3µA, it must be tied to IN if unused, and it cannot be driven below GND unless tied to IN. |
| 8 | GND | power_in | Ground pin, where the bottom of the output-setting resistor divider should connect directly for optimum regulation, and which must be tied to exposed pad pin 9 and the PCB ground. |
| 9 | GND | power_in | Exposed pad, which must be tied directly to pin 8 and to the PCB ground and must be soldered to the PCB for enhanced thermal performance. |
