5V 0.5A Regulated Power Supply Circuit
Power supply is the heart of any electronic circuit, without stable voltage the circuit will fail; sometimes 7805 IC is not enough and also sometimes current requirement is higher, therefore, discrete regulator is useful. This 5V 0.5A Regulated Power Supply Circuit gives 5V output at 0.5A current and it uses TIP3055 transistor and IC TL431 […]
Transistor Based 5V Linear Power Supply Circuit
A power supply is vital in electronics because most circuits require a stable DC voltage. Since the mains supply provides AC voltage, the power supply must convert this alternating current into the direct current that sensitive components rely on to function This Transistor Based 5V Linear Power Supply Circuit gives regulated 5 volts DC and […]
5V Regulated Power Supply Circuit using Transistors
A 5V regulated power supply is very important in electronics because it runs many digital circuits, such as microcontrollers, sensors, and logic ICs; also this 5V regulated power supply circuit using transistors provides a stable 5V DC output. The circuit uses transistors for voltage regulation, which allows it to handle more current than IC regulators, […]
12V Battery Low Voltage Alarm Circuit
Batteries play an important role in many electronic systems; however, their voltage drops over time, and if it falls too low, the battery may become damaged. So low voltage indication needed. Therefore, this 12 V Battery Low Voltage Alarm Circuit protects the battery by providing visual and audible alerts; also its simple, low-cost design uses […]
Low Voltage Alert Circuit for 9V Battery
Battery power plays an important role in electronic circuits, but the battery voltage can drop without warning; as a result, devices may stop working suddenly, making a low-voltage alarm necessary. This Low Voltage Alert Circuit for 9V Battery gives warning when a 9V battery goes low, as it uses LM339 comparator IC and also uses […]
