FIXED DUAL 500mA LOW DROPOUT POSITIVE REGULATOR
DESCRIPTION
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.
APE8839 is dual low dropout positive regulator with

... The input pin of regulator. Typically a minimum of 1uF 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 1.5V higher than Vout in order for the device to regulate properly. No function APE8839 3 ...
