L78M10CDT

Introduction

The L78MC10CDT is a high-efficiency, low-cost, low-dropout linear voltage regulator, optimally designed to provide stability in power supplies up to 1.5A. It provides an output voltage of +10V, with a maximum input voltage of +15V. It features 200 mV typical dropout voltage, low quiescent current, high drive capability, and low output noise. This device is suited for off-line power supplies applications such as electronic appliances and home audio/visual devices.

Application Field

The L78MC10CDT can be used for a variety of portable electronic devices, including mobile phones, laptop PCs, digital cameras, and portable gaming systems. It is designed to provide a high-efficiency and low-noise power supply for these devices. It is also suitable for automotive, industrial, and medical applications. In addition, the device is suitable for low-voltage and high-current auxiliary power supplies, adjustable current sources, and adjustable voltage sources.

Working Principle

The L78MC10CDT is a power supply device that uses the principle of linear regulation. It regulates the output voltage by using a feedback loop to compare the output voltage to a reference voltage. If the output voltage deviates from the reference voltage, the regulator will adjust the output voltage level to match the reference voltage. This is accomplished by varying the resistance of a transistor, known as the pass transistor, to control the amount of current flowing through it.

The L78MC10CDT is equipped with several advanced features. It has a high-precision output voltage that can be trimmed within 5mV to 10V. It also has built-in overcurrent and overtemperature protection. Furthermore, it has very low quiescent current, high drive capability, and low dropout voltage. Compared to traditional power regulators, the L78MC10CDT can significantly reduce power dissipation in low-noise applications.
