CAUTION: Stresses above those listed in “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress only rating and operation of the
device at these or any other conditions above those indicated in the operational sections of this specification is not implied.
IMPORTANT NOTE: All parameters having Min/Max specifications are guaranteed. Typical values are for information purposes only. Unless otherwise noted, all tests
are at the specified temperature and are pulsed tests, therefore: T_J = T_C = T_A
Electrical Specifications V+ = +5V, V- = GND, V_FB+ = 1/2V+, T_A = +25°C, unless otherwise specified. Boldface limits apply over the
operating temperature range, -40°C to +125°C.
