LM4040/D
LM4040, LM4041
Precision Micro-Power
Shunt Voltage References
Description
LM4040 and LM4041 are precision two−terminal shunt mode
voltage references offered in factory programmed reverse breakdown
voltages of 1.225 V, 2.500 V, 3.000 V, 3.300 V, 4.096 V, and 5.000 V.
ON Semiconductor’s Charge Programmable floating gate
technology ensures precise voltage settings offering five grades of
initial accuracy; from 0.1% to 2%.
LM4040 and LM4041 operate over a shunt current range of 60 mA
to 15 mA with low dynamic impedance, and 100 ppm/°C temperature
coefficient ensuring stable reverse breakdown voltage accuracy over a
wide range of operating conditions.
These shunt regulators do not require an external stabilizing
capacitor but are stable with any capacitive load (up to 1 mF).
Offered in space saving SOT−23 and SC−70 packages LM4040 and
LM4041 are specified for operation over the full industrial
temperature range of −40°C to +85°C.
