Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | OUT | power_out | Regulator output that must be bypassed to ground with a 0.47 µF or larger capacitor and connected together with pin 2 for proper operation. |
| 2 | OUT | power_out | Regulator output that must be bypassed to ground with a 0.47 µF or larger capacitor and connected together with pin 1 for proper operation. |
| 3 | NR | passive | Noise reduction pin, which can be bypassed with a 10 nF to 100 nF capacitor to reduce output noise, and left unconnected if not used. |
| 4 | GND | power_in | Ground pin for the regulator. |
| 5 | SD | input | Shutdown pin per the Table 5 label 'Active Low'; the regulator is disabled when it is connected to ground, the ON threshold is 2.0 V minimum and the OFF threshold is 0.3 V maximum, and it should be tied to the input pin if shutdown is not used. |
| 6 | ERR | output | Open collector error flag output that goes low to warn the output is about to leave regulation, with a low output voltage of 0.3 V maximum at a 400 µA sink and leakage of 13 µA maximum at 5 V. |
| 7 | IN | power_in | Regulator input that must be connected to pin 8 for proper operation, with an input supply range of 3.2 V to 12 V and an absolute maximum of 16 V. |
| 8 | IN | power_in | Regulator input that must be connected to pin 7 for proper operation, with an input supply range of 3.2 V to 12 V and an absolute maximum of 16 V. |
