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.
