LM4120AIM5X-5.0/NOPB

具有使能引脚的 1.2V 和可调节、0.2%、50ppm/°C 温漂、精密串联基准电压 5-SOT-23 -40 to 85

Description

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.
