MC1403 2.5V PRECISION SERIAL VOLTAGE REFERENCE .. .. OUTPUT VOLTAGE : 2.5V ±1% INPUT VOLTAGE RANGE : 4.5V to 40V QUIESCENT CURRENT : 1.2mA typ. OUTPUT CURRENT : 10mA N DIP8 (Plastic Package) D SO8 (Plastic Micropackage) DESCRIPTION The MC1403 is a serial 2.5V bandgap voltage reference. The major advantages are the 1% precision, the wide input voltage range (4.5V to 40V) and the low quiescent current (1.5mA max.)
