Precision Micropower Shunt Voltage Reference in bare die form

Description
The LM4040B-1.2 is a high precision, two-terminal
shunt mode, bandgap voltage reference with fixed
reverse breakdown voltage of 1.225V. The device is
ideal for space-critical high reliability applications with
initial 0.2% accuracy and 100ppm/°C max temperature
coefficient. A 45μA to 12mA shunt current capability
with low dynamic impedance ensures stable reverse
breakdown voltage accuracy over a wide current range
and operating temperature. No external stabilizing
capacitors are required.

Features:
0.2% (max) output voltage tolerance at 25°C
15ppm/°C typical temperature coefficient at 25°C
Wide operating current range 45μA to 12mA
No output capacitor required
Tolerates capacitive load
Bandgap reference corrects temperature drift
Specified over military temperature range.
