The MD52E33QA3 is a voltage regulator (LDO) by Mingda that is in an industry-standard SOT-23-3L surface-mount package. It is RoHS compliant and designed for a wide input voltage range, up to 30V. It supports 40mA to 500mA load current. The device is a low-noise, low-dropout, voltage regulator with an excellent voltage regulation accuracy of ±0.5%. A main feature of the MD52E33QA3 is its high performance to size ratio. It has a small form factor and will easily integrate into most designs. It has excellent EMI performance, making it perfect for applications requiring noise-free operation and fast response times. The MD52E33QA3 has built-in over-voltage, over-temperature, and over-current protection and has built-in short-circuit protection. It is suitable for consumer, automotive, industrial, and communication applications.
