TS4041
1.225V MICROPOWER SHUNT VOLTAGE REFERENCE
■1.225V TYP OUTPUT VOLTAGE
■ULTRA LOW OPERATING CURRENT : 65μA maximum at 25°C
■HIGH PRECISION @ 25°C +/- 2% +/- 1% +/- 0.5%
■HIGH STABILITY WHEN USED WITH CAPACITIVE LOADS
■INDUSTRIAL TEMPERATURE RANGE: -40 to +85°C
■150ppm/°C MAXIMUM TEMPERATURE COEFFICIENT
DESCRIPTION
The TS4041 is a low power shunt voltage reference providing a stable 1.225V output voltage over the industrial temperature range (-40 to +85°C). Availabe 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 TS4041 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
