TS4040
2.5V MICROPOWER SHUNT VOLTAGE REFERENCE
■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 reference 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 saving 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
