LTL431APKLT1G

LRC LESHAN RADIO COMPANY,LTD. Programmable Precision Reference S-LTL431XXKLT1G DESCRIPTION The S-LTL 431 is a three-terminal adjustable regulator with a guaranteed thermal stability over applicable temperature ranges. The output voltage may be set to any value between Vref(approximately 2.5V) and 36V with two external resistors. It provides very wide applications, including shunt regulator, series regulator, switching regulator, voltage reference and others. SOT-23 1: Cathode; 2: Ref; 3: Anode FEATURES         Low Dynamic output impe dance 0.1Ω (Typ) Adjustable output voltage Fast turn-on response Sink current capability of 0.1mA to 100mA Low output noise Industrial temperature range Excellent temperature coefficient 25ppm/°C S- Prefix for Automotive and Other Applications Requiring Unique Site and Control Change Requirements; AEC-Q100 Qualified and PPAP Capable.
