PRODUCTION DATA
Refer to the PDF data sheet for device specific package drawings
The regulator has an internal MOSFET that connects a pulldown resistor between the output and ground when the device is disabled. This connection actively discharges the output voltage. The active discharge circuit is activated by the enable pin or by the voltage on IN falling below the undervoltage lockout (UVLO) threshold.
Do not rely on the active discharge circuit for discharging a large amount of output capacitance after the input supply collapses. Reverse current flow from the output to the input potentially causes damage to the device. Limit reverse current to no more than 5% of the device rated current for a short period of time.
