The MIC5393-FMYMT-TR is a three-terminal, positive-voltage linear regulator designed to provide well-regulated outputs with very low noise, ripple, and high output current in a voltage regulator. It features adjustable output voltage, current limit protection, and thermal shutdown protection. It is a versatile device that is suitable for a wide range of applications, including battery chargers, DC-DC converters, and systems that require low noise and high current outputs.

The MIC5393-FMYMT-TR combines a voltage reference, an operational amplifier, and a series pass element with integrated current limiting into a single package. It has a low quiescent current of 15uA, a fast transient response, and an output voltage adjustable between 1.2V and 6V. The output voltage is determined by the setting of two external resistors, and the current limiting function is set by adjusting the input voltage. The over-current protection and the thermal shutdown protection are incorporated in the device to prevent damage from overload.

The MIC5393-FMYMT-TR can be used to provide regulated DC power in various systems and is beneficial for applications where a precise, low noise, and low ripple voltage is needed. Due to its current limit and thermal shutdown circuit, it is particularly suitable for applications that require a high load current, such as powering high-current loads, powering microprocessors, and providing stable voltages for precision analog circuits. Its adjustable current limiting and over-temperature protection provide an additional layer of safety.

In order to use the MIC5393-FMYMT-TR, three external resistors are needed to control the output voltage and current limit. The output voltage is set by a voltage divider, which consists of two external resistors. The current limit is set by an internal reference voltage, which is determined by the input voltage. In order to reduce power dissipation within the device, a heatsink is recommended in applications where the current is over 1A.

The MIC5393-FMYMT-TR is an efficient and versatile voltage regulator suitable for a wide range of applications, including battery chargers, DC-DC converters, and low-noise, high-current systems. It has adjustable current limit and thermal shutdown, making it ideal for applications that require high current and robust protection. The output voltage can be precisely set by two external resistors, and the device is easy to operate. In addition, its low quiescent current and fast transient response make it suitable for low-power applications.
