MIC2920A-3.3BS TR Application Field and Working Principle

The MIC2920A-3.3BS TR is a voltage regulator from the family of linear voltage regulators, designed and manufactured by the company Micrel Semiconductor. It is designed to provide regulated output voltages and eliminate the need for multiple supply voltages.The MIC2920A-3.3BS TR is a device specifically designed for direct power supply regulation in digital systems such as PDAs, cell phones, and other consumer electronic products. It is a three-terminal integrated high input-voltage, low-dropout, linear voltage regulator that operates from a 4.5V to 15V input voltage range. The integrated output voltage is adjustable from 2.5V to 5.5V. The device is designed to deliver up to 1A of output current.The MIC2920A-3.3BS TR is designed using advanced BiCMOS processing techniques, which provide for greater accuracy and stability compared to the traditional linear regulators. The device also features a minimum output voltage drop of only 1V at light load levels, making it ideal for applications that require low-power operation.The MIC2920A-3.3BS TR operates on the principle of Linear Voltage Regulation, which is based on the use of a voltage feedback loop and a series voltage regulating element. This feedback loop constantly monitors and controls the output voltage, adjusting it as necessary to maintain a constant output voltage.The internal linear regulator of the MIC2920A-3.3BS TR is provided with various safety features, such as over-current protection, temperature protection, and thermal shutdown. These safety features allow the regulator to protect the system it is powering and ensure that it runs trouble free.The MIC2920A-3.3BS TR offers excellent performance and reliability by employing advanced BiCMOS processing techniques, providing better accuracy and stability compared to traditional linear voltage regulators. The device is designed to generate an adjustable output voltage ranging from 2.5V to 5.5V and to deliver up to 1A of output current. It is suitable for direct power supply regulation in digital systems such as PDAs, cell phones, and other consumer electronic products due to its low-power operation and minimum dropout voltage characteristics. Finally, its integrated safety features protect the system from over-current and over temperature conditions.
