Stable regulation of output voltage is an operational imperative of linear regulators. While this topic has been discussed in the past (Reference 1 and Reference 2), this article provides a practical, ...

In this article, we focus on two key application-oriented parameters of the linear regulator: Power Supply Ripple Rejection (PSRR) and output noise. These parameters have been discussed before (see ...

[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 ...

Some of the many low-dropout (LDO) regulators supplying voltage regulation for electronic systems are designed for low noise. For example, the IC in Figure 1 achieves an RMS noise voltage of about 115 ...
