It integrates a synchronous rectifier, which keeps efficiency high at light loads — a key advantage for battery-powered or always-on rails where every milliwatt matters. The 2 MHz switching frequency lets you use a small inductor and ceramic output capacitors, shrinking the total solution footprint. Rated for -40°C to 125°C junction temperature, it suits industrial sensors, automotive body electronics, and portable instrumentation that must keep running in hot enclosures or under-hood environments. ## 50 mA output — the design constraint At 50 mA maximum output, this regulator is sized for low-power auxiliary rails — think always-on microcontroller standby supply, CAN transceiver bias, or a sensor front-end. It is not a main-rail converter for a motor drive or a high-current FPGA core. If your BOM needs more than 50 mA, the ADP5302 family (same pinout, same 2 MHz switching, same package) offers a higher current rating while keeping the same footprint and control loop characteristics. ## Synchronous rectification and light-load efficiency The integrated synchronous rectifier replaces the usual Schottky catch diode with a low-Rds(on) FET. At 50 mA output, that saves several hundred milliwatts of diode conduction loss compared to an asynchronous design. For a device that spends most of its life in a few-milliamp sleep state, that efficiency gain directly extends battery life or reduces thermal buildup in a sealed enclosure. ## Lifecycle and sourcing The ADP5304ACPZ-1-R7 carries an Active lifecycle status with ROHS3 compliance. It is available through independent distribution and can be quoted to order against an RFQ; current pricing and stock levels are confirmed at quote time. For dual-sourcing or a higher-current option, the ADP5302ACPZ-2-R7 shares the same package and switching frequency, though its output current rating differs — verify the fit against your load budget before substituting.","metaTitle":"ADP5304ACPZ-1-R7 Buck Regulator, 50 mA, 2 MHz, 10-LFCSP","metaDescription":"ADI ADP5304ACPZ-1-R7 step-down buck regulator, 50 mA output, 2 MHz switching, synchronous rectifier, -40°C to 125°C, 10-LFCSP.
