Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | IN | power_in | Input pin that supplies power to the regulator; tie all IN pins together and to the exposed backside pad, and an input bypass capacitor of 2.2µF to 4.7µF generally suffices. |
| 2 | IN | power_in | Input pin that supplies power to the regulator; tie all IN pins together and to the exposed backside pad, and an input bypass capacitor of 2.2µF to 4.7µF generally suffices. |
| 3 | IN | power_in | Input pin that supplies power to the regulator; tie all IN pins together and to the exposed backside pad, and an input bypass capacitor of 2.2µF to 4.7µF generally suffices. |
| 4 | ILIM | input | Current limit programming pin; a resistor between ILIM and IN sets the limit (nominal scale factor 10A•kΩ), ILIM must not be driven more than 0.3V below IN, and it should be tied to IN if unused. |
| 5 | IMONP | output | Positive current monitor pin that sources current equal to 1/2000 of output current into a resistor to GND, must be at least 2V below IMONN, and must not be driven more than 0.3V below IN; tie to IN if unused. |
| 6 | IMONN | output | Negative current monitor pin that sinks current equal to 1/1000 of output current through a resistor to GND, must be at least 2V above IMONP for positive monitoring, and must not be driven more than 0.3V below IN; tie to GND if unused. |
| 7 | SHDN | input | Bidirectional shutdown pin referenced to GND that turns the output off within ±0.45V of GND and on beyond ±1.4V, must not be floated, and must not be driven more than 0.3V below IN. |
| 8 | SET | input | Inverting error amplifier input and regulation setpoint that receives a precision 50µA current; a resistor from SET to GND programs the output voltage, and SET must not be driven more than 0.3V below IN. |
| 9 | GND | power_in | Ground pin that supplies the quiescent current and NPN pass transistor drive current, and must not be driven more than 0.3V below IN. |
| 10 | OUT | power_out | Output pin that supplies power to the load; tie all OUT pins together, use a minimum 4.7µF output capacitor with ESR below 0.5Ω, and do not drive it more than 0.3V below IN. |
| 11 | OUT | power_out | Output pin that supplies power to the load; tie all OUT pins together, use a minimum 4.7µF output capacitor with ESR below 0.5Ω, and do not drive it more than 0.3V below IN. |
| 12 | OUT | power_out | Output pin that supplies power to the load; tie all OUT pins together, use a minimum 4.7µF output capacitor with ESR below 0.5Ω, and do not drive it more than 0.3V below IN. |
| 13 | IN | power_in | Exposed backside pad that is electrically connected to IN and the device substrate; it must be soldered to the PCB for proper electrical and thermal performance. |
