SPX2945 系列 3.3 V 400 mA 低压差稳压器 - SOT-223-3
Use the LDO linear regulator from EXAR to maintain a constant output voltage. Its typical dropout voltage at current is 0.06@1mA|0.36@400mA V. It has an overall accuracy of ±1 %. This voltage regulation device"s single output can produce a current up to 0.4 A. By only needing an input voltage of 4.1 V with a maximum of 30 V, this is the best way to control the power in your circuit. With a fixed output that has a voltage of 3.3 V, this is power management at its best. At a load regulation of 20mV and line regulation of 20mV a constant current can be produced at the output of your circuit. This component will be shipped in tape and reel packaging to allow for effective mounting and safe delivery. The maximum dropout voltage is 0.1@1mA|0.45@400mA V. Its polarity is positive. This voltage regulation device has an operating temperature range of -40 °C to 125 °C.
