G5ULM2596数据手册GTM中文资料规格书

描述 Description

The  G5ULM2596  series  of   regulators  are  monolithic  integrated  circuits  that  provide  all  active  functions  f or  a  step-down  (buck)  switching regulator , capable  of  driving 3A load  with  excellent line  and  load  regulation. These devices  are  available in fixed  output  voltage  of  3.3v , 5v , 12v  and  an  adjustable  output  version.  Requiring  a  minimum  number  of   external  components,  these  regulators  are  simple  to  use  and include internal frequency compensation and a fixed-frequency oscillator .
