Additional Details

The R1210N501D-TR utilizes a CMOS process to achieve low supply current and high accuracy. The built-in overcurrent protection feature employs a foldback circuit, reducing the output current in the event of a short circuit to protect the IC and connected components. The thermal shutdown circuit disables the output when the junction temperature exceeds a certain threshold, preventing damage from overheating. The DFN(PLP)4-10 package provides excellent thermal dissipation and allows for easy mounting on PCBs. This regulator is suitable for applications requiring a stable 5.0V supply with minimal power consumption and a small footprint.
