The CMS detector will see the replacement of its existing endcap calorimeter with a new high granularity calorimeter (HGCAL), which will need to withstand much higher radiation levels than the present endcaps. This poses tight constraints on the front-end electronics, including the powering chain. As part of this chain, a low-dropout linear regulator (LDO) has been designed and prototyped for post-regulation for HGCAL, providing extremely low noise stable power to the analog front-end. We present results from tests of the LDO, including from a detailed irradiation campaign (TID, SEE, neutrons)..
