How to Choose a Voltage Regulator for Your PCB Design

Voltage regulators are one of the most important decisions in any power design. This guide explains the main regulator families and the specifications you should check before requesting a quote.

LDO vs Buck vs Boost

LDO regulators are simple and low-noise, ideal for low dropout and low-current rails. Buck converters step voltage down efficiently, while boost converters step voltage up. Hybrid parts and modules add flexibility when board space is limited.

Key Specifications

• Input voltage range
• Output voltage and current
• Efficiency at your load point
• Quiescent current
• Package and thermal performance
• Input/output capacitors recommended by the vendor
