5S Seagate Microelectronics Limited 5 AMP, 3-TERMINAL, FIXED POSITIVE VOLTAGE REGULATORS The IPiR1I8AAP3R18A and IP1R18/1P3R18 series of fixed three terminal positive regulators are capable of delivering 5 amps of load current, and are available with several convenient output voltage options. The A-suffix devices provide 0.01%/ line regulation, 0.5% load regulation, and a +1% output voltage tolerance at room temperature. Over all specified operating conditions (load, line, power, and temperature), the output voltage is guaranteed not to vary by more than +3%, Protection features include safe operating area current limiting for the output power transistor, and thermal shutdown. The entire series of regulators is available in a TO-3 package, and the commercial version is also available in a convenient, low cost plastic TO-218 package.
