Overview

The Scalable LDO (Low Drop Out) Regulator macro addresses typical SOC power supply and other voltage regulation needs in a fully integrated easy-to-use macro.

The LDO is comprised of two macros which includes the ‘Control’ and ‘Unit’ blocks. The ‘Unit’ blocks are scalable to the customer’s current requirement. The LDO macro includes an internal bandgap style voltage reference circuit which is used as a reference to compare the voltage supplies against. Alternately, the output voltage may be programmed to be proportional to the input supply or other reference voltage.
