■ 2.5V OUTPUT VOLTAGE ■ ULTRA LOW CURRENT CONSUMPTION: 40µA TYP. ■ HIGH PRECISION @ 25°C ±2% and ±1% ■ HIGH STABILITY WHEN USED WITH CAPACITIVE LOAD ■ INDUSTRIAL TEMPERATURE RANGE: -40 to +85°C ■ 150ppm/°C MAXIMUM TEMPERATURE COEFFICIENT

DESCRIPTION

The TS4040 is a low power shunt voltage refer- ence providing a stable 2.5V output voltage over the industrial temperature range (-40 to +85°C). Available in SOT23-3 surface mount package, it can be designed in applications where space sav- ing is a critical issue. The low operating current is a key advantage for power restricted designs. In addition, the TS4040 is very stable and can be used in a broad range of application conditions. APPLICATION ■ Computers ■ Instrumentation ■ Battery chargers ■ Switch Mode Power Supply ■ Battery operated equipments ORDER CODE Z = TO92 Plastic package - also available in Bulk (Z), Tape & Reel (ZT) and Ammo Pack (AP) LT = Tiny Package (SOT23-3) - only available in Tape & Reel (LT) PIN CONNECTIONS (top view) Precision TO92 SOT23-3 SOT23 Marking 2% TS4040EIZ-2.5 TS4040EILT-2.5 L243 1% TS4040DIZ-2.5 TS4040DILT-2.5 L242 Single temperature range: -40 to +85°C Z TO92 (Plastic Package) L SOT23-3L (Plastic Micropackage) TS4040 2.5V MICROPOWER SHUNT VOLTAGE REFERENCE March 2002
