The 20 mA output current ceiling means it can source a modest load directly, while the 10 µA minimum cathode current is the floor below which the reference drops out of regulation, so the series resistor from the supply must be sized to keep at least 10 µA flowing even at no load. ## TO-92-3 package — board-fit and thermal reality The TO-92-3 (TO-226AA) through-hole package is the same three-lead transistor outline used for decades — the pinout is standard (cathode, anode, no-connect), so it drops into existing footprints without a layout change. Temperature drift is specified at 20 ppm/°C typical — over the full 70°C span that adds about 1.7 mV of shift on the 1.235 V output, which is tight enough for a 0.1% system but not for a sub-0.05% metrology reference.","metaTitle":"LT1004CZ-1.2#PBF Shunt Reference, 1.235 V, ±0.3%, TO-92","metaDescription":"Analog Devices LT1004CZ-1.2#PBF shunt voltage reference, 1.235 V fixed output, ±0.3% tolerance, 20 mA output, TO-92-3.

The AD589JH also carries 5 µVrms noise (10 Hz to 10 kHz) versus 60 µVrms for the LT1004. They are not pin-compatible drop-ins without checking the bias resistor and load requirements — the AD589JH's tighter noise comes at the cost of much looser initial accuracy and half the drive current."},{"question":"What is the LT1004CZ-1.2#PBF's tolerance and package?","answer":"The LT1004CZ-1.2#PBF is specified at ±0.3% tolerance in a TO-92-3 (TO-226AA) through-hole package, supplied in bulk."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/LT1004CZ-1.2~4PBF","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/LT1004CZ-1.2~4PBF when reusing this data.
