The MAX8515AEZK-T comes in a TSOT-23-5 thin package, a 5-lead surface-mount profile that shares the same 2.90 x 2.80 mm footprint as the standard SOT-23-5 but with a lower seated height. The supplier device package is listed as TSOT-23-5, so the reel label and the part marking both reference the thin variant — confirm the pad geometry matches the TSOT-23-5 land pattern before placing it alongside taller SOT-23 devices on the same paste stencil.
Adjustable shunt reference — output range and cathode current
This is a shunt-type voltage reference with an adjustable output from 0.6 V up to 18 V, set by two external resistors. The output can source or sink up to 20 mA, while the minimum cathode current for regulation is 4 mA — below that the reference may drop out of spec, so the bias resistor from the supply rail must be sized to keep at least 4 mA flowing through the device across the full load range.
