SBVS310C July 2017 – June 2019 TLV743P
The enable pin (EN) is active high. Enable the device by forcing the EN pin to exceed VEN(HI). Turn off the device by forcing the EN pin to drop below VEN(LO). If shutdown capability is not required, connect EN to IN. There is no internal pulldown resistor connected to the EN pin.
The TLV743P device has an internal pulldown MOSFET that connects a 120-Ω resistor to ground when the device is disabled. The discharge time after disabling depends on the output capacitance (COUT) and the load resistance (RL) in parallel with the 120-Ω pulldown resistor. The time constant is calculated in Equation 1:
