APE8842 fixed dual 600ma low dropout positive regulator features description 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 : 3.3v/1.8v for a version 3.3v/1.2v for c version (depend on bottom exposed pad size & vin voltage) sop-8 with exposed pad need only 1uf mlcc for stability application pc peripheral communication data and specifications subject to change without notice 1 201103021 typical application package / ordering information APE8842 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/1.8v or 3.3v/1.2v, logic supply. APE8842 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.
