mic2214 micrel, inc. m9999-101705 10 october 2005 input capacitor good bypassing is recommended from input to ground to help improve ac performance. a 1f capacitor or greater located close to the ic is recommended. bypass capacitor the internal reference voltage of the mic2214 can be by - passed with a capacitor to ground to reduce output noise and increase power supply rejection (psrr). a quick-start feature allows for quick turn-on of the output voltage regardless of the size of the capacitor. the recommended nominal bypass capacitor is 0.01f, but it can be increased without limit. output capacitor each regulator output requires a 1f ceramic output capaci - tor for stability. the output capacitor value can be increased to improve transient response, but performance has been optimized for a 1f ceramic type output capacitor. x7r/x5r dielectric-type ceramic capacitors are recom - mended because of their temperature performance. x7r-type capacitors change capacitance by 15% over their operating temperature range and are the most stable type of ceramic capacitors. z5u and y5v dielectric capacitors change value by as much as 50% and 60% respectively over their operat - ing temperature ranges. to use a ceramic chip capacitor with y5v dielectric, the value must be much higher than an x7r ceramic capacitor to ensure the same minimum capacitance over the equivalent operating temperature range. adjustable regulator design vout1 adj1 r1 r2 adj2 vout2 r2 r1 gnd mic2214 adjustable regulator design the mic2214 allows the programming of the output voltages 1 and 2 anywhere between 1.25v and 5.5v, the maximum operating rating of the part. two resistors are required for each output. appropriate resistor values are required to prevent the low quiescent current performance being compromised. resistor values recommended are between 100k and 500k. the resistor values are calculated by: r1 = r2 1.250 C 1 v out where v out is the desired output voltage. calculate sepa - rately for each output.
