In this condition, VIN will equal the pulled-up output (should output be pulled-up.) 4、 When input voltage (VIN) rises above the ground voltage (GND) level, output will be unstable at levels below the minimum operating voltage (VMIN). Between the VMIN and detect release voltage +VDET) levels, the ground voltage (GND) level will be maintained. 5、 When input voltage (VIN) rises above detect release voltage (+VDET), output voltage (VOUT) will be equal to VIN. 6、 The difference between +VDET and –VDET represents the hysteresis range. Timing Chart： ME2804XX: Directions for use： 1、 Please use this IC within the stated maximum ratings. Operation beyond these limits may cause degrading or permanent damage to the device. 2、In order to stabilize the IC’s operations, please ensure that VIN pin’s input frequency’s rise and fall times are more than several u Sec/V.
