MIC5311

MIC5311 LowQ™ Mode Dual 300mA LDO General Description The MIC5311 is a high performance, dual µCap low dropout regulator offering ultra-low operating current and a second, even lower operating current mode, LowQ™ mode, reducing operating current by 75%. Each regulator can source up to 300mA of output current maximum. Ideal for battery operated applications, the MIC5311 offers 1% accuracy, extremely low dropout voltage (60mV @ 150mA), and low ground current (typically 28µA total). When put into LowQ™ mode, the internal current draw drops down to 7µA total. The MIC5311 also comes equipped with a TTL logic compatible enable pin that allows the part to be put into a zero-offmode current state, drawing no current when disabled. The MIC5311 is a µCap design, operating with very small ceramic output capacitors for stability, reducing required board space and component cost. The MIC5311 is available in fixed output voltages in the 3mm x 3mm MLF-10 leadless package. Data sheets and support documentation can be found on Micrel’s web site at www.micrel.com.
