Additional Details

The TCR2EF25 features a typical dropout voltage of 110mV at 150mA output current, enabling it to operate efficiently even when the input voltage is close to the output voltage. The low quiescent current of 4.2µA (typical) minimizes power consumption in standby mode, contributing to longer battery life. The device incorporates overcurrent protection and overtemperature protection circuits to prevent damage from overload conditions. The DFN4 package (1.0mm x 1.0mm x 0.38mm) offers a compact solution for space-constrained applications. The TCR2EF25 utilizes a CMOS process, ensuring high performance and reliability. It is designed to be stable with ceramic capacitors, further simplifying the design process.

The TCR2EF25 is particularly well-suited for applications that require a stable and efficient 2.5V power supply, such as powering microcontrollers, sensors, and other low-voltage components in portable devices. Its protection features and small size make it a versatile and reliable choice for a wide range of electronic applications.
