Datasheet LM4041 (Diodes)

LM4041 PRECISION MICROPOWER SHUNT VOLTAGE REFERENCES Description Pin Assignments
The LM4041 is a bandgap circuit designed to achieve a
LM4041_F (SOT23)
precision micro-power voltage reference of 1.225 V. The CATHODE 1 device is available in the small outline SOT23 and SC70-5 3 N/C surface mount packages which are ideal for applications where space saving is important. ANODE 2 Both packages are available to 0.5% C grade and 1% Pin 3 must left floating or connected to pin 2. D grade for precision applications. Excellent performance is maintained over the 60µA to 12mA operating current range
LM4041_ADJF….(SOT23)
with a typical temperature coefficient of only 20ppm/°C. The REF 1 device has been designed to be highly tolerant of capacitive loads so maintaining excellent stability. 3 ANODE This device offers a pin for pin compatible alternative to the CATHODE 2 LM4041 voltage reference in both adjustable and 1.225V output variants.
