描述 Description

The LM4125 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 2V and up to 6V consuming 160 μA (Typ.) supply current. In power down mode, device current drops to less than 2 μA.The LM4125 comes in two grades (A and Standard) and three 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 tempco of 50ppm/°C ensured from ?40°C to +125°C. The very low dropout voltage, low supply current and power-down capability of the LM4125 makes 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 specs are ensured over the extended temperature range (?40°C to +125°C). Please contact TI for full specifications over the extended temperature range. The LM4125 is available in a standard 5-pin SOT-23 package.
