Usually, a linear (LDO) or switch-mode voltage regulator will do the trick.<\/li><li class=\"ace-line ace-line old-record-id-VMrXdIMLYowHbbxn5D6cX4pVnJc\">Although linear regulators lower noise in the output, they generate more heat that requires an active cooling system. These devices work adequately in lower noise applications, for instance, audio applications, but extra heat dissipation designs become necessary.<\/li><li class=\"ace-line ace-line old-record-id-UY5nd0wjvozA82xliXPcFFtznGF\">Switching-mode regulators provide high efficiency over a current range, although the switching action may cause spiking in the output response.
