MIC5211 Dual μCap 80mA LDO Regulator
●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.
The µCap regulator design is optimized to work with low-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 ßeta PNP™ technology to prolong battery life. When disabled, 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, and 5.0V versions. Certain mixed voltages are also available. Contact Micrel for other voltages.
