TS822 2.5V MICROPOWER SHUNT VOLTAGE REFERENCE s 2.50V TYP. OUTPUT VOLTAGE s ULTRA LOW CURRENT CONSUMPTION: s HIGH PRECISION @ 25°C 40µA TYP. ±2% (Standard version) ±1% (A grade) s HIGH STABILITY WHEN USED WITH CAPACITICE LOAD s INDUSTRIAL TEMPERATURE RANGE: -40 to +85°C s 100ppm/°C MAXIMUM TEMPERATURE COEFFICIENT DESCRIPTION The TS822 is a low power shunt voltage reference providing a stable 2.5V 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 TS822 is very stable and can be used in a broad range of application conditions.
