What does the 30 mA output and ratiometric charge pump mean for your design?
The MAX868EUB+T: That 30 mA ceiling is the continuous load limit — for a sensor bias or op-amp rail that draws 20 mA, this part clears the budget with margin, but anything above 30 mA requires a different topology or external pass element. The switching frequency sweeps from 270 kHz to 630 kHz. At the low end, switching losses drop but the output ripple is higher — the downstream LDO or filter capacitor must be sized for the worst-case ripple at the lowest frequency the part settles at under your load.
Package, temperature range, and board-fit constraints
Housed in a 10-TFSOP/10-MSOP (0.118", 3.00 mm width) package with a supplier device package of 10-uMAX/uSOP. This is a fine-pitch, low-profile footprint — the 0.50 mm lead pitch demands a controlled reflow profile and a stencil aperture that deposits enough paste on the narrow lands without bridging. Available in Tape & Reel (TR) or Cut Tape (CT). The TR quantity is the standard reel count for this package; CT is suitable for prototype or low-volume builds where full reel buy is not justified.
Lifecycle and compliance status — what to expect for BOM planning
Analog Devices lists the MAX868EUB+T as Active and ROHS3 Compliant. No official successor or pin-compatible cross-reference is published by Analog Devices for this order code. If a second source is required, the parametric match must be verified against the ratiometric function and fixed -Vin/2Vin output — most generic charge pumps offer adjustable or inverter-only outputs and will not drop in without a board change.
