Supply range and output — rail planning
The input range from 1.8 V to 5.5 V lets this reference run off various rails, but the output is fixed at 1.263 V. The 1 mA maximum output current limits the load.
Package and mounting — board-level fit
The SOT-23-3 (TO-236-3 / SC-59) package is a three-pin surface-mount footprint common for small-signal transistors and references. No special pad layout beyond the standard SOT-23 land pattern; keep the trace short to the ADC reference pin to minimize noise pickup.
Note that the part is marked RoHS non-compliant, which may affect its use in markets with RoHS enforcement — verify your exemption or accept the non-compliant status.
