MC78LC33HT1G Application Field and Working Principle

MC78LC33HT1G devices, developed by ON Semiconductor, are three-terminal, low-dropout (LDO) voltage regulators. This device is particularly well-suited for applications where very low quiescent current is required such as battery-operated systems. Typical applications include local on-card regulation, input/output supply regulation, and logic power regulation. The MC78LC33HT1G device is a low-dropout linear IC containing a power transistor and a reference source. HOpin is the input, Vout is the output, and GND is the ground for the complete circuit. The voltage regulator IC features a 0.1V dropout voltage and an output current at least 1.5 A. It has an externally adjustable current limit and an internally set thermal limit. The device operates from an input voltage of 2.25 V to 10 V. It also features low operating current, low output noise, and temperature stability of 0.02%. It is available in SOIC-8 and TO-220-7 packages. The shift of output voltage is bound to the positive difference between the input and output voltages. The minimum drop-out voltage of the MC78LC33HT1G device is 0.1V at rated output current, 0.2 mA quiescent input current and over 1.5 A output current. It can provide up to 1.5 A output current with 0.1 V dropout voltage. The current limit is externally adjustable and thermal limit is internally set.The MC78LC33HT1G devices feature excellent error rate characteristics which make them suitable for applications requiring low input and output noise. They are suitable for use in precision voltage regulation designs, applications requiring low maximum quiescent current and applications requiring compliance to international standards. It is designed to adjust the output voltage from the reference source with minimum power dissipation. The highest ripple attenuation is achieved through the current limiting feature with the assistance of the soft start and the output voltage control pins. Applications of MC78LC33HT1G devices include supplying power to precision analog and digital electronics like programmable logic controllers, microcontrollers and other application specific ICs that require precise power supply. They can also be used in battery-operated systems, LED drive and power conversion applications.In summary, the MC78LC33HT1G devices are low-dropout linear ICs containing a power transistor and a reference source. They feature a 0.1V dropout voltage and an output current of at least 1.5A and a maximum of 2A. They feature good error rate characteristics and are suitable for use in precision voltage regulation designs, applications requiring low maximum quiescent current and applications requiring compliance to international standards. Typical applications include local on-card regulation, input/output supply regulation, and logic power regulation.
