1 / 6 page AIC1084 5A Low Dropout Positive Adjustable Regulator Analog Integrations Corporation 4F, 9, Industry E. 9th Rd, Science Based Industrial Park, Hsinchu Taiwan, ROC www.analog.com.tw DS-1084-03 Sep 21, 01 TEL: 886-3-5772500 FAX: 886-3-5772510 1 n FEATURES l Dropout Voltage 1.3V at 5A Output Current. l Fast Transient Response. l Extremely Tight Line and Load Regulation. l Current Limiting and Thermal Protection. l Adjustable Output Voltage or Fixed 1.5V, 1.8V, 3.3V. l Standard 3-Pin Power Packages. n APPLICATIONS l Mother Board I/O Power Supplies. l Microprocessor Power Supplies. l High Current Regulator. l Post Regulator for Switching Supply. n DESCRIPTION The AIC1084 is a low dropout three terminal regulator with 5A output current capability. The output voltage is adjustable with the use of a resistor divider or fixed 3.3V. Dropout voltage is guaranteed to be at maximum of 1.4V 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. n TYPICAL APPLICATION CIRCUIT C2 10µF VOUT 3.3V VIN 5V + + VREF RF2 205Ω 1% ADJ AIC1084 C1 10µF 2 3 1 RF1 125Ω 1% V REF=VOUT - VADJ =1.25V (typ.) V OUT =VREF x (1+RF2/RF1)+ IADJ x RF2 I ADJ =55µA (typ.) (1) C1 needed if device is far away from filter capacitors. (2) C2 required for stability. Adjustable Voltage Regulator C2 10µF VOUT 3.3V VIN 5V + + GND C1 10µF AIC1084-33 2 1 3 Fixed Voltage Regulator |
