50ppm/°C Precision Micropower Shunt Voltage
References with Multiple Reverse Breakdown Voltages
General Description
The LM4050/LM4051 are precision two-terminal, shunt-
mode, 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 space-criti-
cal applications, the LM4050/LM4051 are offered in the
subminiature 3-pin SC70 surface-mount packages
(1.8mm x 1.8mm), 50% smaller than comparable
devices in SOT23 surface-mount package (SOT23 ver-
sions are also available).
Laser-trimmed resistors ensure excellent initial
accuracy. With a 50ppm/°C temperature coefficient,
these devices are offered in three grades of initial accu-
racy ranging from 0.1% to 0.5%. The LM4050/LM4051
have a 60µA to 15mA shunt-current capability with low
dynamic impedance, ensuring stable reverse break-
down voltage accuracy over a wide range of operating
temperatures and currents. The LM4050/LM4051 do
not require an external stabilizing capacitor while
ensuring stability with any capacitive loads.
The LM4050/LM4051 specifications are guaranteed
over the temperature range of -40°C to +125°C.
