2 / 10 page Ultra-Low Output Voltage, Low-Quiescent-Current Linear Regulator for High-Temperature Applications 2 _______________________________________________________________________________________ ABSOLUTE MAXIMUM RATINGS DC ELECTRICAL CHARACTERISTICS (For devices with VOUT ≤ 1.5V, VIN = 3.3V. For devices with VOUT > 1.5V, VIN = 5V. EN = IN, TJ = -40°C to +125°C, CIN = 1µF, COUT = 4.7µF, CCRES = 1000pF, unless otherwise noted. Typical values are at TA = +25°C.) (Note 1) Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
