微功率80V线性稳压器

LT3010小封装提供了高性能，可在以前需要预调整或复杂的开关电源应用的高压轨中实现低功率。低静态电流最小化功耗。内部保护电路省去了外部保护二极管。8引脚MSOP封装提供了低热阻，使其易于应用在恶劣的环境中。advertisement80VLinearRegulatorisMicropowerDesignNote314ToddOwenIntroductionrunningfromahighvoltagerail.Theonlyexternalcompo-Industrial,automotiveandtelecomapplicationsposenentsrequiredareinputandoutputbypasscapacitors,toughdesignchallengesduetoharshoperatingenviron-andtheinputbypassisnotrequiredifthedeviceislocatedmentsandlargevoltagetransientsonalreadyhigh(12Vcloseenoughtothemainsupplybypasscapacitor.Inter-to48V)rails.SomeswitchingpowersuppliesarerobustnalfrequencycompensationontheLT3010stabilizestheenoughtoprovidelocalizedlowvoltage/highcur
