ZHCSIW6L October 2000 – October 2018 LM4040-N , LM4040-N-Q1
PRODUCTION DATA.
The LM4040 device is a fixed output voltage part, where the feedback is internal. Therefore, the part can only operate is a closed loop mode and the output voltage cannot be adjusted. The output voltage will remain in regulation as long as IR is between IRMIN, see Electrical Characteristics: 2-V LM4040-N VR Tolerance Grades 'A' And 'B'; Temperature Grade 'I', and IRMAX, 15 mA. Proper selection of the external resistor for input voltage range and load current range will ensure these conditions are met.
