1 Gnral Dscription Th is a micropowr 2-trminal band-gap voltag rgulator diod. It oprats ovr a 30µA to 20mA currnt rang. Each circuit is trimmd at wafr sort to provid a ±0.50% and ±0.80% initial tolranc. Th dsign of th allows for a larg rang of load capacitancs and oprating currnts. Th low start-up currnt maks ths parts idal for battry applications. Functional Block Diagram VR offrs this part in a TO-92 and SOP-8 packags as wll as th spac saving SOT-23.
