SC4041

PRECISION SHUNT VOLTAGE REFERENCE PRELIMINARY - April 13, 1998 SC4041 TEL:805-498-2111 FAX:805-498-3804 WEB:http://www.semtech.com DESCRIPTION The SC4041 is a two terminal precision voltage reference with thermal stability guaranteed over temperature. The very low fixed output voltage of 1.225 V is ideal for use with today’s low voltage integrated circuits. The SC4041 has a typical dynamic output impedance of 0.25Ω. Active output circuitry provides a very sharp turn on characteristic - the minimum operating current is 60µA, with a maximum of 20mA. Available with five voltage tolerances (0.1%, 0.2%, 0.5%, 1.0% and 2.0%) and three package outlines (SOT-23, SO-8 and TO-92), this part allows the designer the opportunity to select the optimum combination of cost and performance for their application.
