... EN turn on control level must be lower than 0.4V to assure the RT9198A LDO regulator switch on. The RT9198A LDO regulator will go into shutdown mode when the voltage on the EN pin is higher than 1.2 V. The RT9198A equips a quick-discharge function to protect the system. When the regulator is turned off by EN pin, the internal MOSFET between V discharge output voltage quickly ...
