• High Output Voltage Accuracy 0.05%
reference, having exceptionally high initial accuracy
• Low Temperature Coefficient 10 ppm/°C
(0.05%) and temperature stability (10ppm/°C). The
• Extended Temperature Operation -40-125°C
LM4030 is available with fixed voltage options of 2.5V
and 4.096V. Despite the tiny SOT-23 package, the
• Excellent Thermal Hysteresis, 75ppm
LM4030 exhibits excellent thermal hysteresis
• Excellent Long-Term Stability, 40ppm
(75ppm) and long-term stability (40ppm) as well as
• High Immunity to Board Stress Effects
immunity to board stress effects.
• Capable of Handling 50 mA Transients
The LM4030 is designed to operate without an
