SBVS338E March 2020 – December 2021 TPS7A20
The enable (EN) input polarity is active high. The output voltage is enabled when the voltage of the enable input is greater than VEN(HI) and disabled when the enable input voltage is less than VEN(LOW). If independent control of the output voltage is not needed, connect EN to IN.
This device has a smart enable circuit to reduce quiescent current. When the voltage on the enable pin is driven above VEN(HI), as listed in the Electrical Characteristics table, the device is enabled and the smart enable internal pulldown resistor (REN(PULLDOWN)) is disconnected. When the enable pin is floating, the REN(PULLDOWN) is connected and pulls the enable pin low to disable the device. The REN(PULLDOWN) value is listed in the Electrical Characteristics table.
