Fabricated on a n Dropout voltage of 240 mV (typical) at 3A load current CMOS process, the device operates from two input voltages: n Precision Output Voltage across all line and load VBIAS provides power for the internal bias and control circonditions: cuits, as well as drive for the gate of the N-MOS power — ± 1.0% for TJ = 25˚C transistor, while VIN supplies power to the load. The use of — ± 2.0% for 0˚C ≤ TJ ≤ +125˚C an external bias rail allows the part to operate from ultra low — ± 3.0% for -40˚C ≤ TJ ≤ +125˚C VIN voltages. Unlike bipolar regulators, the CMOS architecn Over-Temperature and Over-Current protection ture consumes extremely low quiescent current at any outn Available in 5 lead TO-220 and TO-263 packages put load current. The use of an N-MOS power transistor n Custom VOUT values between 0.8V and 1.2V are results in wide bandwidth, yet minimum external capacitance available is required to maintain loop stability. n -40˚C to +125˚C Operating Temperature Range The fast transient response of this device makes it suitable for use in p...
