Product details

Supply range and power gating

Operates from a single 2.25V to 3.6V supply, covering 2.5V and 3.3V logic rails without a separate regulator.

Housed in a 6-SMD, no-lead package measuring 5.00 mm x 3.20 mm with a seated height of 0.90 mm — a standard 5x3.2 mm footprint that matches many quartz oscillator pads, simplifying a drop-in swap on existing layouts. Surface-mount assembly with no exposed pad; the four corner pads carry the signal and supply, while the two centre pads are no-connect — verify the PCB land pattern matches the 6-pin assignment before committing.

Frequently asked questions

How does the Enable/Disable function work on the DSC1121?

When the Enable pin is pulled low (or left floating with an internal pull-up), the output is disabled and enters a high-impedance state, reducing supply current from 35 mA to 22 mA typical.
