Description
The TS4041 is a low power shunt voltage reference providing a stable 1.225V output voltage over the industrial temperature range (-40°C to +85°C). Availabe in SOT23-3 surface mount package, it can be designed in applications where space saving is critical. 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. L SOT23-3L (Plastic micropackage) Pin connections (Top view)
1 Absolute maximum ratings and operating conditions
Table 1. Absolute maximum ratings (AMR)
- P d is calculated with Tamb = 25°C and Tj = 150°C and Rthja = 340°C/W for the SOT23-3L package.
- Human body model: 100pF discharged through a 1.5k Ω resistor between two pins of the device, done for
all couples of pin combinations with other pins floating.
- Machine model: a 200pF cap is charged to the specif ied voltage, then discharged directly between two pins
combinations with other pins floating. Table 2. Operating conditions
