To assure the LDO regulator will switch on, the ambient temperature for fixed TJ(MAX) and thermal EN turn on control level must be greater than 1.4 volts. resistance θJA. The LDO regulator will go into the shutdown mode when the voltage on the EN pin falls below 0.4 volts. For to protecting the system, the 6219 have a quick-discharge function. If the enable function is not needed in a specific application, it may be tied to VIN to keep the LDO regulator in a continuously on state.
