The HG7550M3-1/TR with SOT-23-3 Linear Voltage Regulators (LDO) ROHS manufactured by HGSEMI is a surface mount, low-power, low-dropout (LDO) voltage regulator. The device features a high-accuracy output voltage (50uV typical) and small form factor, which makes it ideal for space-constrained applications. The HG7550M3-1/TR operates with a wide input voltage range from 1.5V to 8V, and offers a wide output voltage range from 0.8V to 5V. It can provide up to 400mA of output current at a 0.1 ohm dropout voltage to 5V. The device features low-noise operation, reverse-current protection, thermal shutdown, and built-in over-current protection. The package is compliant with RoHS environmental regulations, and is halogen-free.
