... Internal current and thermal limiting protection are provided by the presence of a short circuit at the output and an internal thermal shutdown circuit. The MC33375 has a control pin that allows a logic level signal to turn−off or turn−on the regulator output. Due to the low input−to−output voltage differential and bias current ...

... Storage Temperature Range Stresses exceeding Maximum Ratings may damage the device. Maximum Ratings are stress ratings only. Functional operation above the Recommended Operating Conditions is not implied. Extended exposure to stresses above the Recommended Operating Conditions may affect device reliability.

... V (1.8 V Option) out THERMAL SHUTDOWN Thermal Shutdown 1. Low duty pulse techniques are used during test to maintain junction temperature as close to ambient as possible. 2. Quiescent Current is measured where the PNP pass transistor is in saturation. V MC33375 Series = 1.0 mF 25°C, for min/max values ...

... V, 2.5 V, 3.0 V, and 3.3 V output voltage options. Output voltage options of 5.0 V require only 0.22 mF for stability. The output capacitor must be mounted as close as possible to the MC33375. If the output capacitor must be mounted further than two centimeters away from the MC33375, then a larger value of output capacitor may be required for stability ...
