The MD52A28PA1 is a SOT89-3 Linear Voltage Regulators (LDO) ROHS manufactured by Mingda. It is a 3-terminal, low drop-out voltage regulator which provides an output voltage as precise as ±1% while consuming very little quiescent current. The LDO features ultra-low dropout voltage, excellent line/load regulation, and high PSRR for improved noise immunity, making it ideal for power supply applications. The MD52A28PA1 is also RoHS compliant and features reverse current protection, over-current protection, short-circuit protection, and thermal shutdown protection for increased safety and reliability.
