MIC2212-SJBML-TR

The MIC2212-SJBML-TR is a high performance, low quiescent current, low dropout linear regulator from Micrel Incorporated. It is suitable for a wide range of applications, such as in automotive, industrial, communications and consumer electronics. The device is capable of supplying up to 0. 395A of output current. It is offered in three package options: SOP-8, TSSOP-3x3 and TO-252-5.

The MIC2212-SJBML-TR has a wide input voltage range from 2.5V to 5.5 V and an adjustable output voltage up to 5.5 V, and can maintain +/-2% output voltage accuracy. Its at load dropout voltage is typically 140mV and has a low quiescent current of 30µA over the specified input and output range. Thermal shutdown protection, short circuit protection and current limit protection helps maintain system stability and aids fault protection. It is also AEC-Q100 qualified.

The working principle of the MIC2212-SJBML-TR is based on a low dropout (LDO) linear regulation principle. It uses an internal voltage reference and a linear pass element, usually a PMOS transistor to regulate the output voltage. The regulator compares the output voltage with the internal reference, and adjusts the gate voltage of the pass element to maintain the output voltage at the reference. In other words, the current flowing through the pass element is used to control the voltage across it. This allows the output voltage to remain at a constant level regardless of loading conditions.

Using the MIC2212-SJBML-TR in automotive, industrial, communications and consumer electronics applications offer advantages such as ease of system layout, reduced component count, improved power efficiency and reduced noise. In automotive applications, it can provide reliable power for critical functions such as engine control units (ECUs) and sensor modules. In industrial applications, it can supply power to products such as process controllers, variable speed drives and environmental monitoring systems. In communications applications, it can supply power to transceivers, logic controllers and base band processors, while in consumer applications such as mobile phones and portable music players, it can ensure reliability and increase power efficiency. The MIC2212-SJBML-TR is an ideal solution for supply stable power in any application.

In conclusion, the MIC2212-SJBML-TR is a low dropout linear regulator from Micrel Incorporated designed to provide a reliable and stable power supply for automotive, industrial, communications and consumer electronics applications. It has a wide input voltage range and adjustable output voltage up to 5.5 V, and also has protective features such as thermal shutdown, current limit and short circuit protection for fault protection. Its low quiescent current and low dropout voltage provides improved power efficiency and reduced noise making it the ideal choice for any application requiring a stable power supply.
