The APL5523 is a dual low dropout regulator with output1 with 3.3V/0.5A and output2 with 1.8V/0.3A output capability. It is optimized for lower dropout voltage and faster transient response, making it ideal for low voltage applications. The regulator comes in a SOP-8 and SOP-8-P package.
The APL5523 is a dual-channel linear regulator designed for desktop computers and networking systems. It features two independent output channels: Output 1 provides 3.3V at up to 500mA, while Output 2 provides 1.8V at up to 300mA. The device includes built-in thermal protection, current limit protection, and fast transient response.
| Output 1 Voltage | 3.3V |
|---|---|
| Output 1 Current | 500mA |
| Output 2 Voltage | 1.8V |
| Output 2 Current | 300mA |
| Input Voltage Range | 2.7 to 6 V |
