Key Specifications
Product Description
The UM1470 series of linear regulators are ultralow, quiescent current devices designed for power-sensitive applications. A precision band-gap and error amplifier provides 2% accuracy over temperature. Quiescent current of only 1 μA makes these devices ideal solutions for battery-powered, always-on systems that require very little idle-state power dissipation. These devices have thermal-shutdown, current-limit, and reverse-current protections for added safety. The shutdown current in this mode goes down to 150nA, typical. The UM1470 series is available in SOT23-5 and SOT89-3 packages.
