In Figure 1, the 5V linear regulator (U1) delivers as much as 150mA of load current when operating by itself. Operating with the external pass transistor shown (Q1), the circuit maintains 5V ...
[Kevin Darrah] wanted to make a simple 3.3V regulator without using an integrated circuit. He wound up using two common NPN transistors and 4 1K resistors. The circuit isn’t going to beat out a cheap ...
Linear Technology’s 1.5-A LT3081 low-dropout (LDO) linear regulator targets industrial applications (Fig. 1). Today’s designers already have a plethora of switching regulator options, but Linear CTO ...
What are typical applications for a low dropout (LDO) linear regulator? LDO linear regulators are usually employed in systems that require a low-noise power source instead of a switching regulator ...
