The MIC2950-05YZ TR is a linear voltage regulator from Microchip’s PMIC-Voltage Regulators-Linear family of products. It is a 5V low-dropout linear voltage regulator, ideal for use in mobile applications that are powered by a single-cell li-ion battery. The MIC2950 ensures continuous, stable output voltage, regardless of the magnitude and polarity of the input current. The MIC2950 is designed to deliver excellent line and load regulation, and also offers better output noise and ripple performance than most low-dropout linear regulators.

The MIC2950-05YZ TR can be used in many different applications, including digital-signal processors (DSPs), personal digital assistants (PDAs), mobile phones, handheld computers, portable navigation systems, audio applications, and remote control systems. It is also ideal for use in low-power systems, and is capable of providing up to 200mA of continuous output current. With its low quiescent current and wide operating temperature range, the MIC2950-05YZ TR is an ideal choice for battery-operated applications.

The MIC2950-05YZ TR operates on input voltages of 4.5V to 28V, and has an adjustable output voltage range of 1.23V to 5.0V. It features a typical dropout voltage of 350mV when providing 150mA of current, which makes it a great choice for high-efficiency systems. The MIC2950-05YZ TR also comes with shut-down and overtemperature protection, current limiting, and a power-good signal.

The MIC2950-05YZ TR’s unique working principle is based on a combination of linear regulation and high-efficiency switched-mode control. It utilizes a combination of a linear error amplifier, a high-current P-channel MOSFET, and a current mirror to provide a tight output voltage regulation over a wide input voltage range. The linear error amplifier compares the voltage across the regulated output with a reference voltage, and outputs a signal which is used to control the current that flows through the P-channel MOSFET. The P-channel MOSFET is then switched on and off to regulate the output voltage. The current mirror increases the output current capability while decreasing the output resistance and improving the efficiency of the regulator. The combination of these features allows the MIC2950-05YZTR to provide an efficient and accurate linear voltage regulation.

The MIC2950-05YZ TR is an ideal choice for use in mobile applications that require a low-dropout linear regulator with excellent line and load regulation, low noise and excellent thermal performance. With its 5V output voltage, low quiescent current, wide operating temperature range, and high-efficiency switched-mode control, the MIC2950-05YZ TR provides a reliable, accurate, and efficient voltage regulation solution for battery-operated systems.
