SC4040AS

PRECISION SHUNT VOLTAGE REFERENCE PRELIMINARY - April 13, 1998 SC4040 TEL:805-498-2111 FAX:805-498-3804 WEB:http://www.semtech.com DESCRIPTION The SC4040 is a two terminal precision voltage reference with thermal stability guaranteed over temperature. The SC4040 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. FEATURES • Trimmed bandgap design (0.2%) • W ide operating current range 60µA to 20mA • Low dynamic impedance (0.25Ω) • Available in SOT-23, TO-92 and SO-8 APPLICATIONS • Cellular telephones • Portable computers • Instrumentation • Automotive PIN CONFIGURATIONS SOT-23-3 Lead (Top View) BLOCK DIAGRAM Cathode SO-8 Lead (Top View) Anode SYMBOL DIAGRAM Cathode TO-92 (Top View) Anode 1 © 1998 SEMTECH CORP. 652 MITCHELL ROAD NEWBURY PARK CA 91320 PRECISION SHUNT VOLTAGE REFERENCE PRELIMINARY - April 13, 1998 SC4040 ABSOLUTE MAXIMUM RATINGS Parameter Reverse Current Operating Temperature Range Operating Junction Temperature Range Storage Temperature Range Lead Temperature (Soldering) 10 seconds ESD Rating TA TJ TSTG TLEAD ESD Symbol Maximum 60 µA to 20 -40 to +85 -40 to +150 -65 to +150 260 2 Units mA °C °C °C °C kV ORDERING INFORMATION PACKAGE 0.1% SOT-23-3L SO-8 (1) (1)(2) (1) TOLERANCE 0.2% SC4040BSK SC4040BS SC4040BZ 0.5% SC4040CSK SC4040CS SC4040CZ 1.0% SC4040DSK SC4040DS SC4040DZ 2.0% SC4040ESK SC4040ES SC4040EZ T/R Quantity SC4040ASK SC4040AS SC4040AZ 3K 2.5K TR=3K, TA=2K TO-92 Notes: (1) Add suffix ‘TR’ for Tape & Reel.
