LM4050QML
Precision Micropower Shunt Voltage Reference
General Description
Key Specifications
The LM4050QML precision voltage reference is available in
a 10 Lead Ceramic SOIC package. The LM4050QML's de-
sign eliminates the need for an external stabilizing capacitor
while ensuring stability with a capacitive load, thus making the
LM4050QML easy to use. The LM4050-2.5QML has a 60 μA
minimum and 15 mA maximum operating current. The
LM4050-5.0QML has a 74 μA minimum and 15 mA maximum
operating current.
LM4050-2.5QML
■ꢀOutput voltage tolerance IR = 100μA
■ꢀLow temperature coefficient
■ꢀLow output noise
■ꢀWide operating current range
LM4050-5.0QML
±0.1% @ 25°C
15 ppm/°C
50 μVrms(typ)
60 μA to 15 mA
The LM4050QML utilizes fuse and zener-zap reverse break-
down 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 accuracy over a wide range of operating tempera-
tures and currents.
