Tlow = 0°C for MCT78XXC Thigh = +125°C for MCT78XXB, C. When the junction temperature exceeds +125°C, internal current limiting = – 40 °C for MCT78XXB will reduce the output current to less than 1.0 A at a VI–VO of 15 V or greater. The MC7800 die will supply more current under the same conditions. 2. Load and line regulation are specified at constant junction temperature. Changes in VO due to heating effects must be taken into account separately. Pulse testing with low duty cycle is used. |
