DC Switching Voltage Regulators

REG711EA-5/2K5 Description

The REG711EA-5/2K5 is a fixed-output, positive voltage charge pump DC-DC switching regulator from Texas Instruments, designed to deliver a stable 5V output with a maximum current of 50mA. Operating within an input voltage range of 2.7V to 5.5V, this compact regulator leverages a 1MHz switching frequency for efficient power conversion, making it suitable for space-constrained and low-power applications. Packaged in an 8-pin VSSOP and supplied in Tape & Reel (TR), it is optimized for automated surface-mount assembly. The device features a non-synchronous charge pump topology, ensuring simplicity and reliability while maintaining ROHS3 compliance and REACH unaffected status.
