FUNCTIONAL BLOCK DIAGRAM Terminal Functions TERMINAL I/O DESCRIPTION NAME NO. GND 3 Ground ENABLE 1 I Enable input IN 2 I Input supply voltage RESET 5 O/I This terminal is the RESET output terminal. When used with a pullup resistor, this open-drain output provides the active low RESET signal when the regulator output voltage drops more than 5% below its nominal output voltage. The RESET delay time is typically 200 ms. OUT 4 O Regulated output voltage 4 |
