LM4125 Precision Micropower Low Dropout Voltage Reference November 2003 LM4125 Precision Micropower Low Dropout Voltage Reference General 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 guaranteed from −40˚C to +125˚C.
