Precision Micropower Shunt Voltage Reference
General Description
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.
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.
The LM4050QML operates over the temperature range of
-55°C to +125°C.
