DESCRIPTION
The US3036 IC provides an 8 pin low cost switching controller with true short circuit protection all in a compact 8 pin surface mount package, providing a low cost switching solution for applications that require a simple switching regulator from the 5V input where there is no other supply available. One type of such application is generating 2.5V standby from the dual 5V(5V and 5V standby) for the next generation processors.
