mc78fc00 series http://onsemi.com 4 applications information introduction the mc78fc00 micropower voltage regulators are specifically designed with internal current limiting and low quiescent current making them ideal for battery powered applications. an input bypass capacitor is recommended if the regulator is located an appreciable distance ( 4 inches) from the input voltage source. these regulators require 0.1 f capacitance between the output terminal and ground for stability. most types of aluminum, tantalum or multilayer ceramic will perform adequately. solid tantalums or other appropriate capacitors are recommended for operation below 25 c. the bypass capacitors should be mounted with the shortest possible leads or track lengths directly across the regulator input and output terminals. with economical electrolytic capacitors, cold temperature operation can pose a serious stability problem. as the electrolyte freezes, around ? 30 c, the capacitance will decrease and the equivalent series resistance (esr) will increase drastically, causing the circuit to oscillate. quality electrolytic capacitors with extended temperature ranges of ? 40 to +85 c are readily available. solid tantalum capacitors may be the better choice if small size is a requirement. however, a maximum esr limit of 3.0 must be observed over temperature to maintain stability. figure 6 is a typical circuit application. figure 7 is a current boost circuit which can deliver more than 600 ma. the circuit has no current limiting and the external transistor must be rated for the expected power dissipation. figure 6. typical application 23 v o gnd v in gnd 1 0.1 f 0.1 f mc78fc00 figure 7. current boost circuit 23 v o gnd v in gnd 1 0.1 f 10 f mc78fc00 mjd32c 0.1 f 100 .033 f ordering information device device marking output voltage operating temperature range package shipping ? mc78fc30ht1g 0k 3.0 t a = ? 30 to +80 c sot ? 89 (pb ? free) 1000 / tape & reel mc78fc33ht1g 3k 3.3 mc78fc40ht1g 0l 4.0 MC78FC50HT1G 0m 5.0 ?for information on tape and reel specifications, including part orientation and tape sizes, please refer to our tape and reel packaging specifications brochure, brd8011/d. note: other voltages from 2.0 to 6.0 v, in 0.1 v increments, are available upon request. consult factory for information.
