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 60A 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 3 ANODE loads so maintaining excellent stability. This device offers a pin for pin compatible alternative to the CATHODE 2 LM4041 voltage reference in both adjustable and 1.225V output variants.
