The A6528A is designed for portable RF and wireless applications with demanding performance and space requirements. Because of the built-in low-on-state resistance transistor, the voltage difference is low and the output current is large. External output feedback can easily get the voltage required by customers. To make the load current not exceed the current capacity of the output transistor, the functions of over-current protection, over-temperature protection, and short circuit protection are built in.
A6528A supports a high-voltage (20 V) power supply and enables input, and adopts a low-power design, which is suitable for some low-power applications.
The A6528A is available in SOT-25 and SOT89-5 packages.
