Choosing the Right LDO: Beyond the Basic Specs

WebOct 2, 2024 · LDO is a linear voltage regulator that has a small voltage drop between the input and the output, and it works well even when the output voltage is very close to the input voltage unlike the linear voltage regulator that requires a large voltage drop between the input and the output to work properly. The transistor (or other device) is used as one half of a voltage divider to establish the regulated output voltage. The output voltage is compared to a reference voltage to produce a control signal to the transistor which will drive its gate or base. With negative feedback and good choice of compensation, the output voltage is kept reasonably constant. Linear regulators are often inefficient: since the transistor is acting like a resistor, it will waste electrical energy by convertin… opening prayer for christian meeting
