REG71050DDCT

The REG71050DDCT is a 60mA 5V Buck/Boost Charge Pump. A wide input supply voltage makes the REG710 family of device ideal for a variety of battery sources, such as single-cell Li-Ion or 2 and 3-cell nickel-based or alkaline-based chemistries. The input voltage may vary above and below the output voltage and the output remains in regulation. The device works as step-up or step-down converters without the need of an inductor, providing low EMI DC-DC conversion. The high switching frequency allows the use of small surface-mount capacitors, saving board space and reducing cost. The REG710 device is thermally protected and current limited, protecting the load and the regulator during fault conditions. Typical ground pin current (quiescent current) is 65μA with no load and less than 1μA in shutdown mode.
