MIC5201-3.3YM-TR Application Field and Working PrincipleThe MIC5201-3.3YM-TR is a Precision, ±2% low voltage, adjustable and fixed linear voltage regulator that is widely used in different fields in electronics. This voltage regulator ensures the output voltage is within ±2% of the preset value and is intended for use with low-noise, low-power, voltage regulator applications that include active-low enable inputs for power savings.Application FieldThe MIC5201-3.3YM-TR have applications in several areas, including personal digital assistants (PDAs), mobile phones, notebook and desktop computers, digital cameras, hard disk drives, and other consumer electronics. It is designed to provide constant regulated supply voltages for microprocessor systems and other devices requiring a tightly regulated power source.This voltage regulator is ideal for powering small digital systems, as well as embedded applications. It has very low quiescent current, making it ideal for battery-powered or low-power operations.Working PrincipleThe MIC5201-3.3YM-TR consists of an adjustable voltage regulator and a series pass device. The adjustable voltage regulator provides a stable reference voltage to the series pass device, and the adjustable voltage regulator is connected in series with the series pass device.The adjustable voltage regulator typically employs an error amplifier that compares the output of the regulator with a reference voltage and varies the reference voltage as needed to maintain the voltage at its setpoint.In operation, current flows through the series pass transistor from the positive input terminal to the output terminal. As the input voltage rises, the current through the pass device increases to supply the extra current necessary to keep the regulator output voltage constant.The adjustable voltage regulator ensures that the output of the regulator is maintained within ±2% of the preset value. The pass transistor has a low on resistance, typically in the range of 0.5 Ohms to 1 Ohm, that keeps the output voltage drop across the device at a minimum.ConclusionThe MIC5201-3.3YM-TR is a precision, ±2% low voltage, adjustable and fixed linear voltage regulator. This voltage regulator is ideal for powering small digital systems, as well as embedded applications. It has very low quiescent current, making it ideal for battery-powered or low-power operations. The adjustable voltage regulator maintains the output of the regulator within ±2% of the preset value, and the pass transistor has a low on resistance that keeps the output voltage drop at a minimum.
