The MIC5366 includes an auto-discharge feature that is activated when the enable pin is low. The MIC5365/6 is capable of sourcing 150mA output current and offers high PSRR making it an ideal solution for any portable electronic application. Ideal for battery powered applications, the MIC5365/6 offers 2% initial accuracy, low dropout voltage (155mV @ 150mA), and low ground current (typically 29ìA). The MIC5365/6 can also be put into a zero-off-mode current state, drawing virtually no current when disabled. The MIC5365/6 is available in several advanced packages including a lead-free (RoHS compliant) 1mm x 1mm Thin MLF® occupying only 1mm2 of PCB area, a 75% reduction in board area compared to SC-70 and 2mm x 2mm MLF® packages. It is also availabe in an SC-70-5 package. The MIC5365/6 has an operating junction temperature range of –40°C to 125°C. Data sheets and support documentation can be found on Micrel’s web site at www.micrel.com.
