Description

General part information

LM4120 Series

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.
