... MIC5209 General Description The MIC5209 is an efficient linear voltage regulator with very low dropout voltage, typically 10mV at light loads and less than 500mV at full load, with better than 1% output voltage accuracy. Designed especially for hand-held, battery-powered devices, the MIC5209 features low ground current to help prolong battery life ...

... The capacitor can be reduced to 0.47 F for current below 10mA or 0.33 F for currents below 1mA. No-Load Stability The MIC5209 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. ...

... Intel estimates a worst-case load of 320mA. The MIC5209 was designed to provide the 2.5V power requirement for Slot-1 applications. Its guaranteed perfor- mance of 2. 500mA allows adequate margin for all systems, and its dropout voltage of 500mV means that it operates from a worst-case 3 ...

... MIC5209 the MIC5209 is calculated using the voltage drop across the device output current plus supply voltage ground current. Considering worst case tolerances, the power dissipation could be as high as: (V – IN(max) OUT(max) OUT [(3.6V – 2.375V) 320mA] + (3. 407mW D Using the maximum junction temperature of 125 C and a ...
