REG710NA-2.7/250

The REG710NA-2.7/250 from Texas Instruments is a switched-capacitor voltage converter designed to provide a regulated, low-ripple output voltage from an unregulated input. This device features automatic step-up/step-down operation, making it suitable for a wide range of battery sources, including single-cell Li-Ion or multi-cell nickel-based chemistries.

Key electrical specifications include a wide input voltage range of 1.8V to 5.5V, a fixed output voltage of 2.7V, and a maximum output current of 30mA. The device operates at a high switching frequency of 1MHz, which allows for the use of small external capacitors, saving board space and reducing cost. It also features low input and output voltage ripple, and a synchronous rectifier is not required.

Designed for efficiency and reliability, the REG710NA-2.7/250 includes thermal and current limit protection. Its typical quiescent current is 65μA, and it consumes less than 1μA in shutdown mode. The component is housed in a compact SOT-23-6 package, suitable for surface mounting, and operates across a temperature range of -40°C to 85°C.

This charge pump converter is ideal for applications requiring a stable voltage from fluctuating battery inputs without the need for an inductor, minimizing EMI. Its compact size and efficient operation make it suitable for portable communication devices, PDAs, and other space-constrained electronic products.
