1 FEATURES FIXED DUAL 600mA LOW DROPOUT POSITIVE REGULATOR.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 VOUT : 3.3V / 600mA VOUT : V / 600mA (depend on Layout Thermal Pad Size & VIN Voltage) TO-5-5L Package Need only uf MLCC for Stability APPLICATION PC peripheral Communication DESCRIPTION is dual low dropout positive regulator with minimum of 600mA 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/V, logic supply. series are guaranteed to have <.5V dropout at full load current making it ideal to provide well regulated outputs dual channels with up to V input supply, but depend on Power Dissipation Limitation for using. To prevent oscillation, it is recommended to use minimum uf dielectric capacitors for Input/Output Capacitors, In general, the input capacitor in the range of uf to 0uF 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 = /8 from the package. Note: Line and load regulation are guaranteed up to the maximum power dissipation of W. 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 V input/output differential the device is guaranteed to regulate if the output current is greater than 0mA. - % - - % db

3 PIN DESCRIPTIONS PIN SYMBOL GND VOUT / OUT VIN / VIN PIN DESCRIPTION Ground for fix output version The output of the regulator. A minimum of uf capacitor (0mΩ < ESR < Ω) must be connected from this pin to ground to insure stability. The input pin of regulator. Typically a minimum of uf capacitor is connected 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.5v higher than Vout in order for the device to regulate properly. BLOCK DIAGRAM 3
