... MIC5211 General Description The MIC5211 is a dual Cap 80mA linear voltage regulator with very low dropout voltage (typically 20mV at light loads), very low ground current (225 A 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 ...

... C. Tantalum or ceramic capacitors are recommended for operation below –25 C. No-Load Stability The MIC5211 will remain stable and in regulation with no load (other than the internal voltage divider) unlike many other voltage regulators. This is especially important in CMOS RAM keep-alive applications. ...

... Dual-Voltage Considerations For configurations where two different voltages are needed in the system, the MIC5211 has the option of having two independent output voltages from the same input. For ex- ample, a 3.3V rail and a 5.0V rail can be supplied from the MIC5211 for systems that require both voltages. Important ...
