SBVS383A December 2019 – March 2020 TLV752
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.
The TLV752 has an internal pulldown MOSFET that connects an RPULLDOWN 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 pulldown resistor (RPULLDOWN). Equation 1 calculates the time constant:
