onsemi Voltage Regulators - Linear FAN1582D12X

The FAN1582D12X is an ultra-low dropout linear voltage regulator capable of delivering up to 3A of output current. It features a typical dropout voltage of 0.4V at full load, making it suitable for low voltage applications where efficiency is critical. The device supports adjustable output voltages ranging from 1.5V to 5.7V, with fixed options available for specific applications, such as 1.5V and 2.5V outputs for GTL+ bus termination and logic IC operation. The regulator is designed for fast transient response and offers excellent load regulation of 0.05% typical, along with an initial accuracy of 0.5%. It includes on-chip thermal limiting to protect against excessive junction temperatures, ensuring reliable operation under varying load conditions. The FAN1582D12X is available in 5-pin TO-252 DPAK and TO-263 packages, making it suitable for various PCB layouts. This product is ideal for applications such as embedded processor supplies, low voltage logic supplies, and DDR termination.
