NOTE:
1. Parts are 100% tested at +25°C. Over temperature limits established by characterization and are not production tested.
2. VSUPPLY = +5.25V max when VENL = +V (device in disable state).
Electrical Specifications
V+ = +5V, V- = GND, VFB+ = 1/2V+, RL = Open, TA = +25°C, unless otherwise specified. Boldface limits apply
