S9V11X Step Up Step Down Voltage Regulators

Step‑up/step‑down regulators provide a stable output voltage from a wide range of input supplies, making them ideal for battery‑powered boards, sensor modules and small controllers where the supply voltage may vary. They offer adjustable or fixed output levels, integrated low‑voltage cut‑off to protect downstream circuitry, and can deliver modest current while maintaining efficiency even when the input is close to the set voltage. Their compact footprints simplify placement on tight PCBs and they are compatible with common logic families, easing integration into existing designs. Reliability comes from built‑in protection features, and the ability to switch between boost and buck operation reduces the need for separate regulator types in a single project.
