Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | BYP1 | passive | Bypass pin for the channel 1 reference, clamped to ±0.6V from ground, where a maximum 10nF capacitor from OUT1 reduces output noise to a typical 20µVRMS over 10Hz to 100kHz. |
| 2 | NC | unconnected | No connect pin that is not tied to any internal circuitry and may be floated, tied to VIN or tied to GND. |
| 3 | OUT1 | power_out | Channel 1 regulator output supplying up to 500mA, which requires a minimum 3.3µF output capacitor to prevent oscillation. |
| 4 | OUT1 | power_out | Channel 1 regulator output supplying up to 500mA, which requires a minimum 3.3µF output capacitor to prevent oscillation. |
| 5 | GND | power_in | Ground pin that must be tied directly to the exposed pad (pin 17) and to the bottom of the output voltage setting resistor divider for optimum load regulation. |
| 6 | OUT2 | power_out | Channel 2 regulator output supplying up to 500mA, which requires a minimum 3.3µF output capacitor to prevent oscillation. |

| 9 | ADJ2 | input | Channel 2 adjust pin, the error amplifier input held at 1.215V referenced to ground, clamped to ±9V, with a typical 30nA bias current, giving an output range of 1.215V to 19.5V. |
| 10 | SHDN2 | input | Channel 2 shutdown pin where pulling it low turns the channel 2 output off, and it may be left unconnected only as the datasheet describes, with shutdown pin current typically less than 1µA. |
| 11 | IN2 | power_in | Channel 2 input supply pin that powers channel 2 over an input range of 1.8V to 20V and may need a 1µF to 10µF bypass capacitor when far from the main input filter. |
