The SGM2208 is a 3A output current, low noise and low dropout linear regulator whose output voltage is adjusted with a single resistor and the lowest output voltage can be true zero. The SGM2208 can be easily paralleled to increase output current or spread heat on surface mounted boards. The SGM2208 can be widely used in many applications, such as precision large current source and voltage follower, laser diode power supply requiring high current, adjustability to zero and no heat sink.
By using a reference current through a single resistor, the output voltage is programmed to any level. The SGM2208 has the capability to supply a wide output voltage range. The SGM2208 is stable with ceramic capacitors and a 10μF of capacitance on the output that is always used for large output current applications. The SGM2208 also has internal protection functions, such as current limiting and thermal protection.
