MIC5201-4.8BS Voltage Regulator Working Principle and Application Field

The MIC5201-4.8BS is a micropower high-performance regulator specifically designed for high-voltage applications. This voltage regulator is ideal to use in high-impedance circuits where a small current flow and low power dissipation are a priority. It is also suitable for high-speed switching power supplies due to its excellent transient response.The MIC5201-4.8BS is a linear voltage regulator featuring a wide range of input voltage from 4.5V to 18V and adjustable output voltage from 0.8V to 6V. The device is able to maintain tight regulation up to 16V and can deliver up to 100mA of output current with a 10µA maximum quiescent current.Its main advantage is that it offers superior power efficiency and low drop-out voltage. Combined with its high accuracy, it’s an ideal choice for applications such as LED lighting, computer CPUs and GPUs, consumer electronics, automotive, and battery-powered devices. The device features various protective features such as short-circuit protection and over-temperature protection that prevent damage to the device. The MIC5201-4.8BS operates in the range of -40°C to +85°C, making it suitable for a wide range of temperature environments.The working principle of the MIC5201-4.8BS is based on a conventional linear regulator circuit. The device uses an error amplifier to regulate its output voltage by comparing the feedback voltage to an internal reference voltage. The error amplifier amplifies the difference between the 2 voltages and controls a pass element accordingly. The pass element acts as a variable resistor determined by the error amplifier\'s output. This in turn controls the load current, which is proportional to the load voltage. When the load voltage increases, the error amplifier increases the output voltage, thus maintaining a regulated voltage across the load.The MIC5201-4.8BS is one of the most cost-effective and reliable regulators available on the market. It is designed to meet the highest standards of performance, reliability, and cost-efficiency. It is ideal for use in a wide range of applications, from LED lighting to computer CPUs, GPU’s, batteries, automotive and consumer electronics, where accurate voltage regulation is a must.
