Linear Technology switching regulators incorporate synchronous and non-synchronous internal switches. This range offers ultralow noise switching voltage regulators and is suitable in sensitive RF or audio circuit environments. They have a selection of input voltages and switching frequencies with good efficiency. Typical applications include Industrial supplies, wall transformer regulation, automotive battery regulation and distributed supply regulation.
