Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | IN | power_in | Input pin that supplies power to the regulator, withstands reverse voltage relative to GND, OUTS and OUT, and needs a bypass capacitor (4.7µF generally suffices), with IN absolute maximum voltage of ±22V. |
| 2 | IN | power_in | Input pin that supplies power to the regulator, withstands reverse voltage relative to GND, OUTS and OUT, and needs a bypass capacitor (4.7µF generally suffices), with IN absolute maximum voltage of ±22V. |
| 3 | IN | power_in | Input pin that supplies power to the regulator, withstands reverse voltage relative to GND, OUTS and OUT, and needs a bypass capacitor (4.7µF generally suffices), with IN absolute maximum voltage of ±22V. |
| 4 | EN/UV | input | Enable/UVLO pin; pulling it low places the part in shutdown with quiescent current below 1µA, and it turns on with a 1.24V rising threshold and 130mV hysteresis, with absolute maximum voltage of ±22V; do not float it. |
| 5 | PG | output | Open-collector power good flag that pulls low when PGFB is below 300mV, must not be driven more than 0.3V below GND, and should be left floating if power good is not used. |
| 6 | ILIM | passive | Current limit programming pin where a resistor to GND sets the limit with a 150mA·kΩ scale factor, and the pin also monitors current over a 0V to 300mV range; tie to GND if unused and do not drive it more than 0.3V below GND. |
| 7 | PGFB | input | Power good feedback pin where PG goes high above 300mV with 7mV falling hysteresis, it also enables fast start-up, and it must not be driven more than 0.3V below GND; absolute maximum voltage is -0.3V to 22V. |
| 8 | SET | input | Inverting input of the error amplifier and regulation set-point, sourcing a precision 100µA through an external resistor to GND so that VOUT = ISET · RSET over a 0V to 15V output range, with SET voltage limit of -0.3V to 16V. |
| 9 | GND | power_in | Ground pin that must be tied directly to the exposed backside pad, which must be soldered to the PCB ground for proper electrical and thermal performance. |
| 10 | OUTS | input | Output sense non-inverting input to the error amplifier, to be Kelvin connected directly to the output capacitor and load, and must not be driven more than 0.3V below GND; OUTS absolute maximum voltage is -0.3V to 16V. |
| 11 | OUT | power_out | Output pin that supplies power to the load and requires a minimum 10µF output capacitor with ESR below 20mΩ and ESL below 2nH for stability, with OUT absolute maximum voltage of -0.3V to 16V. |
| 12 | OUT | power_out | Output pin that supplies power to the load and requires a minimum 10µF output capacitor with ESR below 20mΩ and ESL below 2nH for stability, with OUT absolute maximum voltage of -0.3V to 16V. |
