REG710NA-3.3/250G4

TEXAS INSTRUMENTS  REG710NA-3.3/250G4  直流-直流开关降压, 升压稳压器, 可调, 1.8 V-5.5 V输入, 3.3V-3.3V输出, 30mA输出, SOT-23-6

The is a 30mA switched-cap DC-DC Converter with fixed 3.3V output. 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.
