Product Description
 
The UM1480S linear regulators is 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. Shutdown mode is enabled by pulling the EN pin low. The shutdown current in this mode goes down to 150nA, typical.  The UM1480S is available in SOT23-5 package.
