LM4050 : Ideal for space critical applications, the LM4050 precision voltage reference is available in the subminiature (3 mm x 1.3 mm) SSOT23 surfacemount package. The LM4050’s design eliminates the need for an external stabilizing capacitor while ensuring stability with any capacitive load, thus making the LM4050 easy to use. Further reducing design effort is the availability of several fixed reverse breakdown voltages: 2.500V, 4.096V, 5.000V, 8.192V, and 10.000V. The minimum operating current increases from 60 µA for the LM40502.5 to 100 µA for the LM405010.0. All versions have a maximum operating current of 15 mA. The LM4050 utilizes fuse and zenerzap reverse breakdown voltage trim during w.
LM4050 : The LM4050/LM4051 are precision twoterminal, shuntmode, bandgap voltage references available in fixed reverse breakdown voltages of 1.225V, 2.048V, 2.500V, 3.000V, 3.3V, 4.096V, and 5.000V. Ideal for spacecritical applications, the LM4050/LM4051 are offered in the sub miniature 3pin SC70 surfacemount packages (1.8mm x 1.8mm), 50% smaller than comparable devices in SOT23 surfacemount package (SOT23 versions are also available). Lasertrimmed resistors ensure excellent initial accuracy. With a 50ppm/°C temperature coefficient, these devices are offered in three grades of initial accuracy ranging from 0.1% to 0.5%. The LM4050/LM4051 have a 60µA to 15mA shuntcurrent capability with low dyn.
LM4050N : Ideal for spacecritical applications, the LM4050N precision voltage reference is available in the subminiature (3 mm × 1.3 mm) SOT23 surfacemount package. The LM4050N design eliminates the need for an external stabilizing capacitor while ensuring stability with any capacitive load, thus making the LM4050N easy to use. Further reducing design effort is the availability of several fixed reverse breakdown voltages: 2.048 V, 2.5 V, 4.096 V, 5 V, 8.192 V, and 10 V. The minimum operating current increases from 60 μA for the LM4050N2.0 to 100 μA for the LM4050N10.0. All versions have a maximum operating current of 15 mA. The LM4050N utilizes fuse and Zenerzap reverse breakdown voltage t.
LM4050NQ1 : Ideal for spacecritical applications, the LM4050N precision voltage reference is available in the subminiature (3 mm × 1.3 mm) SOT23 surfacemount package.

Further reducing design effort is the availability of several fixed reverse breakdown voltages: 2.048 V, 2.5 V, 4.096 V, 5 V, 8.192 V, and 10 V. The minimum operating current increases from 60 μA for the LM4050N2.0 to 100 μA for the LM4050N10.0. All versions have a maximum operating current of 15 mA. The LM4050N utilizes fuse and Zenerzap reverse breakdown voltage t.
LM4050QML : The LM4050QML precision voltage reference is available in a 10Lead Ceramic CLGA package. The LM4050QML's design eliminates the need for an external stabilizing capacitor while ensuring stability with a capacitive load, thus making the LM4050QML easy to use. The LM40502.5QML has a 60 μA minimum and 15 mA maximum operating current. The LM40505.0QML has a 74 μA minimum and 15 mA maximum operating current. The LM4050QML utilizes fuse and zenerzap reverse breakdown voltage trim during wafer sort to ensure that the prime parts have an accuracy of better than ±0.1% at 25°C. Bandgap reference temperature drift curvature correction and low dynamic impedance ensure stable reverse breakdown voltage.

The LM4051N’s advanced design eliminates the need for an external stabilizing capacitor while ensuring stability with any capacitive load, thus making the LM4051N easy to use. Further reducing design effort is the availability of a fixed (1.225V) and adjust able reverse breakdown voltage. The minimum operating current is 60 μA for the LM40511.2 and the LM4051ADJ. Both versions have a maximum operating current of 12 mA. The LM4051N comes in three grades (A, B, and C). The best grade devices (A) have an initial accuracy of 0.1%, wh.
