In order to obtain lower dropout voltage and faster transient response, which is critical for low voltage applications, the APL5223 has been optimized. The dropout voltages are guaranteed at 0.6V at 0.5A for output1 and 0.9V at 0.3A for output 2. Current limit is trimmed to ensure specified output current and controlled shortcircuit current. On-chip thermal limiting provides protection against any bination of overload that would create excessive junction temperatures. The APL5523 regulator es in a SOP-8 and SOP-8P packages.
