The MS79L05 is a SOT-89 Linear Voltage Regulator (LDO) ROHS manufactured by MSKSEMI. It has a maximum output current output of 100mA, a dropout voltage of 0.225V, and an input voltage range of 2.2V to 6.5V. It is a single-channel low dropout voltage regulator designed for applications requiring very low dropout voltage, very low quiescent current, low noise and fast transient response time. The output voltage is adjustable in the range of 1.2V to 5.5V and is internally set at 5V. The device has over-temperature protection, thermal shutdown, and current limiting circuitry. It is RoHS compliant and ideal for automotive and consumer device applications.
