The MIC5202-4.8BM-TR, from Micrel Inc., is a high-performance, high-efficiency, low-noise, low-dropout linear voltage regulator. It is a micro-sized, LDO-based, low-noise power solution for portable, battery-powered and other low-current applications. This voltage regulator features a high-efficiency, low-noise regulator with a maximum dropout voltage of only 2.3mV and a maximum noise of 6μV at 400 kHz for high performance even in the most sensitive systems. In addition, the MIC5202-4.8BM-TR offers an ultra-fast transient response, extremely low quiescent current, and an ultra wide input voltage range of 1.8 to 20V.

The MIC5202-4.8BM-TR is designed to provide adjustable output voltage levels between 0.8V and 5.0V and requires a minimum number of external components. It eliminates the need for expensive adjustable output voltage transformers and can be used with either a fixed output voltage or adjustable voltage. Additionally, the MIC5202-4.8BM-TR features an integrated power good (PG) signal and an over-temperature protection (OTP) circuit for thermal protection.

The MIC5202-4.8BM-TR has a wide range of applications in areas such as industrial, medical, automotive, communications and consumer electronics. It can be used in power management applications such as DC-DC regulators and LED drivers, as well as in mobile and portable equipment where low noise and low dropout voltage are major requirements. In addition, it can be used in battery-powered applications to reduce power consumption and extend battery life.

The working principle of the MIC5202-4.8BM-TR is based on a high-performance low-dropout (LDO) linear voltage regulator, which is formed by replacing the traditional switching regulators with a series-connected LDO. In this configuration, the voltage references are connected to the load, the output voltage is determined by the voltage of the voltage reference, the current passes through the regulator, the regulator receives the output signal from the reference and then output the regulated voltage to the load. This regulator offers a high output accuracy and low noise levels, even in applications with high current and voltage fluctuation.

In summary, the MIC5202-4.8BM-TR is a high-performance, high-efficiency, low-noise, low-dropout linear voltage regulator. It offers an adjustable output voltage range of 0.8V to 5.0V and requires a minimum number of external components. It can be used in efficient power management applications such as DC-DC regulators, LED drivers and battery-powered applications. Its working principle is based on a high-performance LDO linear voltage regulator, thus providing high output accuracy and low noise levels.
