General Description

The TS1537A, TS1537B & TS1537C are low dropout positive voltage regulators with minimum of 1A output current capability. The product is specifically designed to provide well-regulated supply for low voltage IC applications such as high-speed bus termination and low current 3.3V/2.5V (TS1537A) or 3.3V/1.8V(TS1537B) or 2.5V/1.8V(TS1537C) logic supply. This series are guaranteed to have less 1.4V dropout at full load current making it ideal to provide well regulated outputs dual channels with up to 12V input supply.

This series is offered in 5-pin TO-263-5L package.
