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.
