在IEEE中有相關的Journal paper,你可以上去找一下% ?% l9 n8 D$ Q0 u: {/ y
這種capless LDO,最大的困難之處乃在於負載電流處於極大和極小時,它所產生的pole-zero會導致loop stability不穩,故而才會有相關的paper在探討補償方式& i2 ^( b9 b1 x
這方面的paper並不多,而且數學公式也不少作者: jesseyu 時間: 2009-7-14 11:49 PM
For such capless LDO, does it mean that it should use a minimum cap or it won't need any cap but can't sustain too big a cap also?Cause they're dilema
