Description

The EP1017 are adjustable 3-terminal positive voltage regulators capable of supplying in excess of 1.5A over an output voltage range of 1.2 to 37V. These voltage regulators are exceptionally easy to use and require only two external resistors to set the output voltage. Further, they employ internal current limiting. Thermal shutdown and safe area compensation, making them essentially blow-out proof. Pin Assignment

Jun. 2007 www.eorex.com Standard Application ＊Cin is required if regulator is located an appreciate distance from power supply filter. ＊Cout is not needed for stability, however, it does improve transient response. Vout=1.25(1+R2/R1)+IAdjR2 Since IAdj is controlled to less than 100 µA, the error associated with this term is negligible in most applications. ＊Pulse testing required. 1% Duty Cycle is suggested. To calculate R2: Vout=ISETR2+1.250V ; Assume ISET=5.25mA
