Description  
The TS822 is a low power shunt voltage reference  
providing a stable 2.5V 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 TS822 is  
very stable and can be used in a broad range of  
application conditions.

1. Pd is calculated with Tamb = 25°C and Rthja = 340°C/W for the SOT23-3L package  
2. Human body model: 100pF discharged through a 1.5kΩ resistor between two pins of the device, done for  
all couples of pin combinations with other pins floating.  
3. Machine model: a 200pF cap is charged to the specified voltage, then discharged directly between two pins  
of the device with no external series resistor (internal resistor < 5Ω), done for all couples of pin  
combinations with other pins floating.

Package information  
In order to meet environmental requirements, STMicroelectronics offers these devices in  
®
ECOPACK packages. These packages have a lead-free second level interconnect. The  
category of second level interconnect is marked on the package and on the inner box label,  
in compliance with JEDEC Standard JESD97. The maximum ratings related to soldering  
conditions are also marked on the inner box label. ECOPACK is an STMicroelectronics  
trademark. ECOPACK specifications are available at: www.st.com.
