High Efficiency Linear Regulators

by Jim Williams, Linear Technology, Vendor website, Mar 01 1989

Focus:
Pre-regulators circuits improve the efficiency of linear regulators by minimizing the voltage drop across the linear regulator. Pre-regulator circuits are presented for applications with widely varying ac input, dc input, variable voltage output, high current output, ultra high efficiency, or micropower levels.

What you’ll learn:

• How to improve the efficiency of linear regulators using pre-regulator circuits

Notes:
Application Note 32 is based on a manuscript that was originally written for EDN magazine.
