CYStech Electronics Corp. 3A Low Dropout Positive Voltage Regulator Spec. No. : C540E3 Issued Date : 2003.06.24 Revised Date : Page No. : 1/4 PL1085-XXXE3 Features Dropout Voltage 1.3V at 3A Output Current. Fast Transient Response. Extremely Tight Line and Load Regulation. Current Limiting and Thermal Protection. Adjustable Output Voltage or Fixed 1.5V, 1.8V, 2.5V, 2.85, 3.0V, 3.3V, 3.5V, 5.0V. Standard 3-Pin Power Packages. TO-220AB Description The PL1085-XXXE3 is a low dropout three terminal regulator with 3A output current capability. The output voltage is adjustable with the use of a resistor divider or fixed 1.5V, 1.8V, 2.5V, 2.85V, 3.0V, 3.3V, 3.5V and 5.0V. Dropout voltage is guaranteed to be at maximum of 1.3V with the maximum output current. Its low dropout voltage and fast transient response make it ideal for low voltage microprocessor applications. Current limit and thermal protection provide protection against any overload condition that would create excessive junction temperatures. Applications Mother Board I/O Power Supplies. Microprocessor Power Supplies. High Current Regulator. Post Regulator for Switching Supply. Typical Application Circuit Vin=5V Vout=3.3V ADJ C1 10μF VREF R1 125Ω 1% R2 205Ω 1% C2 10μF VREF=VOUT-VADJ=1.25V(typ) VOUT=VREF(1+R1/R2)+IADJ ×R2 IADJ=55µA(typ.) (1)C1 needed if device is far away from filter capacitors. (2)C2 required for stability.
