Choosing a PC Power Supply by Power Comparison
Power supply is probably the most computer components are often overlooked by PCs buyers. However, this component is very important : such as when […]
Positive Regulator with PNP Boost
The IC8211 (Programmable Voltage Detectors) provides the voltage reference and regulator amplifier, while Q1 is the series pass transistor. R1 defines the output current […]
Variable Voltage Regulator based LM117
The regulator circuit uses an LM117K three-terminal adjustable output positive voltage regulator in a TO-3 can. The variable voltage regulator lets you adjust the […]
Variable Zener Diode
This circuit acts like a zener diode with a wide range of voltages. The current passing via the voltage divider R1-R2 is substantially greater […]
Low Voltage Regulators with Short Circuit Protection
These Low Voltage regulators with short circuit protection can provide 6, 7.5, and 9 V from an automobile battery supply of 13.5 V nominal, […]
Linear Power Supply
Every electronic circuit will work as good as its power supply. However this is often overlooked. There are two main families of power supplies: […]
Current Source / Regulator
The Current Source/Regulator circuit powers the load through the regulator’s input rather than its output. Since the regulator’s output sees constant dummy load R1, […]
