Exposure to such conditions may adversely impact product reliability and result in failures not covered by warranty. 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: TJ = TC = TA Electrical Specifications V+ = +5V, V- = GND, VFB+ = 1/2V+, RL = Open, TA = +25°C, unless otherwise specified. Boldface limits apply over the operating temperature range, -40°C to +125°C.
