MIC5216-4.0BM5-TR Application Field and Working Principle

Introduction

The MIC5216-4.0BM5-TR is an Adjustable Linear Voltage Regulator from the MIC5216 family. It is a member of a series of versatile three-terminal adjustable regulators, with built-in protection features such as short-circuit protection, thermal shutdown and current limit. This device is specified for operation over a temperature range of -40°C to 125°C, making it an ideal component for many design configurations. Its small SOT89 package makes it easy to use in small spaces, and its on-chip current limit, short-circuit protection, and thermal shutoff features allow for a very reliable operation.

Application Field

The MIC5216-4.0BM5-TR is suitable for many consumer applications like personal devices, home appliances, audio and others. It can also be used in automotive telematics and control systems, industrial products, and communication systems.

This device can provide adjustable power supply output to many kinds of circuits. With its adjustable output voltage range from 1.21V to 26V and constant current limit up to 1.5A, the MIC5216-4.0BM5-TR is an ideal component for providing a wide range of adjustable output voltages for many applications. It’s small SOT89 package also makes it ideal for space constrained designs.

Working Principle

The MIC5216-4.0BM5-TR is an adjustable linear voltage regulator. The input voltage is applied to the Vin pin and the ground (GND) pin of the MIC5216-4.0BM5-TR. The output voltage is adjusted by the voltage at the ADJ pin. The output voltage can be adjusted from 1.21V to 26V, with a typically voltage accuracy of +0.25V. The output current limit is set by connecting an external resistor between the R1 pin and ground, whose value is related with the output current limit as I_LIMIT = 160/R1 (mA).

The MIC5216-4.0BM5-TR is designed to protect itself and the load in the event of an overload or short-circuit. When the overload or the short-circuit occurs, the current limit function will be activated. The output current will be limited at the current limit set by the external resistor. In addition, when the junction temperature exceeds the thermal shutoff threshold, the output voltage will be forced to 0V.

The MIC5216-4.0BM5-TR’s quiescent current is typically 5mA, which is much lower than conventional discrete solutions. This makes the MIC5216-4.0BM5-TR an excellent choice for power saving designs.

Conclusion

The MIC5216-4.0BM5-TR is an adjustable linear voltage regulator that is suitable for many consumer applications. It has a wide input voltage range (1.21V ~ 26V) with a high output current capability (1.5A). It also has built-in protection functions such as current limit, shortcircuit protection and thermal shutoff, allowing it to remain stable in various harsh environments. Its small SOT89 package is suitable for space constrained designs. The MIC5216-4.0BM5-TR is a great choice for many designs due to its performance, functionalities and reliability.
