Th high staility of this dvic is primarily th rsult of th low tmpratur cofficint Thin Film Rsistor procss and Lasr Trimming of th output voltag at th wafr lvl. Th is availal in a TO9, SOIC8 and SOT89 packag with an oprating tmpratur rang of 0 C to 85 C. A.5 and 5.0 volt dvics ar also availal SPX85.5, SPX Cathod (K) BLOCK IAGRAM + 1.5V Figur 1: Block iagram Anod (A) at: 11/05/0 Micropowr Voltag Rfrnc Copyright 00 Sipx Corporation 1
