Product Summary
The REG7105 is a switched capacitor voltage converter, that produces a regulated, low-ripple output voltage from an unregulated input voltage. A wide-input supply voltage of 1.8V to 5.5V makes the REG7105 ideal for a variety of battery sources, such as single cell Li-Ion, or two and three cell nickel- or alkaline-based chemistries. The applications of the REG7105 include Smart Card Readers, SIM Card Supplies, Cellular Phones, Portable Communication Devices, Personal Digital Assistants, Notebook and Palm-Top Computers, Modems, Electronic Games, Handheld Meters, PCMCIA Cards, Card Buses, White LED Drivers, LCD Displays and Battery Backup Supplies.
