AX1120 Dual 600mA Low Dropout
Regulators
GENERAL DESCRIPTION AX1120 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 logic supply. AX1120 series are guaranteed to have <1.3V 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. The AX1120 is available in the TO252-5L and SOP-8L with exposed pad packages. FEATURES Input voltage range :2.75V to 12V 1.3V maximum dropout at full load current Built-in thermal shutdown Output current limiting for each channel Dual output voltage: VOUT1 is 3.3V/600mA VOUT2 is1.8V/600mA (Depend on layout thermal pad size and VIN voltage) Good noise rejection Fast transient response Low-ESR Ceramic Capacitor(MLCC) Required for Stability Available in the TO252-5L and SOP-8L with exposed pad packages
