The WL2801E25-5/TR is a dropout regulators (LDO) SOT23-5L RoHS manufactured by Will Semiconductor. It is specifically designed for low output current, low input voltage, and low dropout voltage applications. This regulator offers a stable output voltage of 5V with a maximum output current of 250mA. It provides high power efficiency and reliable operations even in harsh environmental conditions. Its small size and high current capability make it ideal for use in consumer electronic, automotive, medical, and industrial applications. The WL2801E25-5/TR has an input voltage range of 1.3V to 20V, a dropout voltage of 500mV typical at full load, a temperature range of -40°C to 125°C, and an efficiency of up to 95%. It is also RoHS-compliant and protected from reverse polarity, overcurrent and over temperature.
