Introduction

The MIC2212-LPYML-TR is a linear low-dropout voltage regulator (LDO) from ON Semiconductor. This voltage regulator is specifically designed to provide low-noise, low-dropout voltage regulation.

Application Field

The MIC2212-LPYML-TR is ideal for applications where a low-noise, low-dropout regulator is required. Typical applications include applications in hard drives, solid-state drives, industrial sensing and control, medical instrumentation, automotive, and telecommunications systems. It can also be used in battery-powered systems, where it provides superb efficiency while regulating the output voltage.

Working Principle

The MIC2212-LPYML-TR voltage regulator works through a five-stage process. First, a power switch controls the voltage input and supplies power to the output terminals. Next, a low-impedance current-sense resistor is used to detect the output voltage. Then, an error-amplifier compares the sensed current to the reference voltage, generating a control signal for the shutdown circuits. In the fourth stage, an adjustable bandgap-based regulator is used to set the internal voltage reference. Finally, the voltage is regulated to accurate levels, and a low-dropout regulator is used to maintain regulation at the output terminals.
