1 / 11 page Dual-Channel, 3.3V/500mA and 1.8V/300mA Linear Regulator Copyright ANPEC Electronics Corp. Rev. A.1 - July., 2004 APL5523 www.anpec.com.tw 1 ANPEC reserves the right to make changes to improve reliability or manufacturability without notice, and advise customers to obtain the latest version of relevant information to verify before placing orders. Features General Description The APL5523 is a dual low dropout regulator with output1 with 3.3V/0.5A and output2 with 1.8V/0.3A output capability. In order to obtain lower dropout voltage and faster transient response, which is criti- cal for low voltage applications, the APL5223 has been optimized. The dropout voltages are guaran- teed at 0.6V at 0.5A for output1 and 0.9V at 0.3A for output 2. Current limit is trimmed to ensure speci- fied output current and controlled short-circuit current. On-chip thermal limiting provides protection against any combination of overload that would create ex- cessive junction temperatures. The APL5523 regu- lator comes in a SOP-8 and SOP-8-P package.
