VOLTAGE REF SERIES 3V SOT-23-5
The LM4120 device is a precision low-power, low dropout bandgap voltage reference with up to 5-mA output current source and sink capability. This series reference operates with input voltages as low as 2 V and up to 12 V, consuming 160-µA (typical) supply current. In power-down mode, device current drops to less than 2 μA. The LM4120 comes in two grades (A and Standard) and seven voltage options for greater flexibility. The best grade devices (A) have an initial accuracy of 0.2%, while the standard have an initial accuracy of 0.5%, both with a temperature coefficient of 50 ppm/°C ensured from −40°C to 125°C. The very low dropout voltage, low supply current, and power-down capability of the LM4120 make this product an ideal choice for battery-powered and portable applications. The device performance is ensured over the industrial temperature range (−40°C to 85°C), while certain specifications are ensured over the extended temperature range (−40°C to 125°C). Contact TI for full specifications over the extended temperature range. The LM4120 is available in a standard 5-pin SOT-23 package.
