Introduction: The MIC69153YME-TR is a high performance 3A adjustable linear voltage regulator used for output current regulation. Developed by Micrel Inc., MIC69153YME-TR features a constant voltage regulation by output current sourcing, temperature status monitoring and has an on-off control as well.

Application Field: MIC69153YME-TR is well suited for a wide variety of applications, such as telecom, consumer electronics, industrial systems, automotive and medical devices. It is the ideal IC for applications that require both current sensing and thermal shutdown functions. It has over current protection, adjustable output voltage from 1 to 18V, dual output current limit and a good line regulation. This device also features a soft-start operation which allows for more reliable and durable operation.

Working Principle: The operating principle for the MIC69153YME-TR is quite simple. A voltage reference is connected to the output and is connected to the control input. This control input is then regulated to the desired output voltage by means of pulse width modulation (PWM) and a feedback circuit. The PWM is generated by the device which then controls the output by means of a switching MOSFET which is connected to the output. The output is monitored by the over current protection (OCP) circuitry, which senses the output current at periodic intervals. If the output current is above or below the pre-set OCP limits, then the output is shut-off and the device enters a protection mode.

Conclusion: In conclusion, the MIC69153YME-TR is a high performance 3A adjustable linear voltage regulator used for output current regulation. It is suitable for a wide range of applications, and features a constant voltage regulation by output current sourcing, temperature status monitoring and an on-off control. The device also features an OCP which senses the output current and shuts off the device if it exceeds pre-set OCP limits. The MIC69153YME-TR is an ideal IC for applications that require both current sensing and thermal shutdown functions.
