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 | BYP2 | passive | Channel 2 reference bypass pin, clamped internally to ±0.6V from ground, with a maximum 0.01µF capacitor recommended for 20µVRMS noise, and must be left unconnected if not used. |+| 2 | ADJ2 | input | Channel 2 error amplifier input, internally clamped to ±7V, with a 30nA bias current flowing into the pin and regulating to 1.22V referenced to ground for an output range of 1.22V to 20V. |+| 3 | SHDN2 | input | Channel 2 shutdown control, where the output turns off when pulled low, must be connected to VIN if unused, and draws a typical pin current of 1µA. |+| 4 | ADJ1 | input | Channel 1 error amplifier input, internally clamped to ±7V, with a 30nA bias current flowing into the pin and regulating to 1.22V referenced to ground for an output range of 1.22V to 20V. |+| 5 | BYP1 | passive | Channel 1 reference bypass pin, clamped internally to ±0.6V from ground, with a maximum 0.01µF capacitor recommended for 20µVRMS noise, and must be left unconnected if not used. |+| 6 | OUT1 | power_out | Channel 1 regulated output, which requires a minimum 1µF output capacitor to prevent oscillations. |+| 7 | SHDN1 | input | Channel 1 shutdown control, where the output turns off when pulled low, must be connected to VIN if unused, and draws a typical pin current of 1µA. |+| 8 | IN1 | power_in | Channel 1 input supply operating from 1.8V to 20V, which withstands reverse voltages of 20V and benefits from a 1µF to 10µF bypass capacitor when far from the input filter. |+| 9 | IN2 | power_in | Channel 2 input supply operating from 1.8V to 20V, which withstands reverse voltages of 20V and benefits from a 1µF to 10µF bypass capacitor when far from the input filter. |+| 10 | OUT2 | power_out | Channel 2 regulated output, which requires a minimum 1µF output capacitor to prevent oscillations. |+| 11 | GND | power_in | Exposed pad ground that must be soldered to the PCB and electrically connected to ground. |++##
