FAQ
What is the function of the EN pin?
The EN pin enables or disables the regulator. Driving it high turns the regulator on, while pulling it low activates shutdown mode.
Does this part have an auto-discharge feature?
No, the AP7315-11W5-7 does not include an auto-discharge feature. For discharge functionality, select the AP7315D variant.
