Advanced Power Electronics Corp. APE8839 FIXED DUAL 500mA LOW DROPOUT POSITIVE REGULATOR FEATURES 1.5V Maximum Dropout at Full Load Current Built-in Thermal Shutdown for Each Channel Output Current Limiting for Each Channel Fast Transient Response Good Noise Rejection Dual Output VOUT1 : 3.3V / 500mA VOUT2 : 1.8V / 500mA (depend on bottom Exposed Pad Size & VIN Voltage) SOP-8 with Exposed Pad DESCRIPTION APE8839 is dual low dropout positive regulator with minimum of 500mA output current capability. The product is specifically designed to provide well-regulated supply for low voltage IC applications such as high-speed bus termination and low current 3.3V/1.8V, logic supply. APE8839 series are guaranteed to have <1.5V dropout at full load current making it ideal to provide well regulated outputs dual channels with up to 12V input supply, but depend on Power Dissipation Limitation for using. To prevent oscillation, it is recommended to use minimum 1uF dielectric capacitors for Input/Output Capacitors, In general, the input capacitor in the range of 1uF to 10uF sufficient.

Line and load regulation are measured at a constant junction temperature by low duty cycle pulse testing. Load regulation is measured at the output lead = 1/18” from the package. Note2: Line and load regulation are guaranteed up to the maximum power dissipation of 2W. Power dissipation is determined by the input/output differentially and the output current. Guaranteed maximum power dissipation will not be available over the full input/output range. Note3: Quiescent current is defined as the minimum output current that requires maintaining regulation. At 12V input/output differential the device is guaranteed to regulate if the output current is greater than 10mA. Note4: Thermal resistance is measured by mounted on a high effective thermal conductivity test board in free air. The bottom exposed pad of ESOP-8 is soldered directly on the PCB. 2 Advanced Power Electronics Corp. APE8839 PIN DESCRIPTIONS PIN SYMBOL GND1 / GND2 VOUT1 / OUT2 PIN DESCRIPTION Ground for fix output version The output of the regulator. A minimum of 1uF capacitor (10mΩ < ESR < 1Ω) must be connected from this pin to ground to insure stability. The input pin of regulator. Typically a minimum of 1uF capacitor is connected VIN1 / VIN2 from this pin to ground to insure that the input voltage does not sag below the minimum dropout voltage during the load transient response. The pin must always be 1.5V higher than Vout in order for the device to regulate properly. Exposed Pad No function BLOCK DIAGRAM 3 Advanced Power Electronics Corp.
