Регуляторы напряжения - Импульсные регуляторы REG711EA-3.3/250

Фиксированный DC/DC преобразователь напряжения с подкачкой заряда , 1.8В до 5.5В вход, 3.3В/50мА

The REG711EA-3.3/250 is a 50mA switched-cap DC/DC Converter produces a regulated, low ripple output voltage from an unregulated input voltage. A wide input supply voltage makes the REG711 ideal for a variety of battery sources, such as single cell Li-Ion or two and three cell nickel or alkaline based chemistries. The input voltage may vary above and below the output voltage and the output will remain in regulation. It works equally well for step up or down without the need for 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 REG711 is thermally protected and current limited, protecting the load and the regulator during fault conditions. Typical ground pin current (quiescent current) is 1mA at full load, 60µA with no load and less than 1µA in shutdown mode. This regulator comes in a thin MSOP-8 package with a component height of less than 1.1mm.
