Description
The SC1458ITS is a dual output, ultra-low dropout linear voltage regulator designed specifically for battery powered wireless applications. It has two versions: SC1458A and SC1458B. The input voltage range required for both versions is between 2.5V and 5.5V. The SC1458A supplies 2.5V on OUTA and 1.8V on OUTB, while the SC1458B supplies 2.85V on both outputs. This component is an ideal choice for applications that require efficient power management and compact size.
