7 / 8 page SG78xxA/78xx PRODUCT DATASHEET Microsemi Analog Mixed Signal Group 11861 Western Avenue, Garden Grove, CA. 92841, 714-898-8121, Fax: 714-893-2570 Page 7 Copyright © 1997 Rev. 1.5, 2010-07-13 TM ® Positive Fixed Voltage Regulator ELECTRI CAL CHARACTERISTICS Unless otherwise specified, these specifications apply over the operating ambient temperatures for SG7815A / SG7815 with -55°C < TA < 125°C, VIN = 23V, IO = 500mA for the K, G and IG – Power Packages, IO = 100mA for the T and L packages, CIN = 0.33µF, and COUT = 0.1µF. Low duty cycle pulse testing techniques are used which maintains junction and case temperatures equal to the ambient temperature.
