| MIC5235 Micrel MIC5235 Ultra-Low Quiescent Current, 150 mA µCap LDO Regulator Final Information The MIC5235 is a 150mA highly accurate, low dropout regulator with high input voltage and ultra low ground current. This combination of high voltage and low ground current makes the MIC5235 ideal for USB and portable electronics applications, using 1-cell, 2-cell or 3-cell Li-Ion battery inputs. A µCap LDO design, the MIC5235 is stable with either ceramic or tantalum output capacitor. It only requires a 2.2µF capacitor for stability. Available in 3.0V and adjustable output voltage verisons, the MIC5235 is offered in the IttyBitty SOT-23-5 package with a junction temperature range of to +125°C. • USB power supply • Cellular phones • Keep-alive supply in notebook and portable computers • Logic supply for high-voltage batteries • Automotive electronics • Battery powered systems Ordering Information Part Number MIC5235-3.0BM5 MIC5235BM5 Marking L230 L2AA Voltage 3.0V ADJ.
