1 / 9 page May 2006 1 MIC5211 MIC5211 Micrel, Inc. General Description The MIC5211 is a dual µCap 80mA linear voltage regulator with very low dropout voltage (typically 20mV at light loads), very low ground current (225µA at 20mA output current), and better than 3% initial accuracy. This dual device comes in the miniature SOT-23-6 package, featuring independent logic control inputs. TheµCapregulatordesignisoptimizedtoworkwithlow-value, low-cost ceramic capacitors. The outputs typically require only 0.1µF of output capacitance for stability. Designed especially for hand-held, battery-powered devices, ground current is minimized using Micrel’s proprietary Super ßetaPNP™technologytoprolongbatterylife.Whendisabled, power consumption drops nearly to zero. Key features include SOT-23-6 packaging, current limiting, overtemperature shutdown, and protection against reversed battery conditions. The MIC5211 is available in dual 1.8V, 2.5V, 2.7V, 2.8V, 3.0V, 3.3V, 3.6V, and 5.0V versions. Certain mixed voltages are also available. Contact Micrel for other voltages.
