The MIC94345-FYCS TR is a low-dropout voltage regulator based on MICREL, Inc.’s fixed flux regulation topology. The regulator is capable of fast transient response with a typical line and load regulation of ±1.0%. The superior transient capability allows it to provide up to 430 mA of output current with low-noise and high-precision output voltage accuracy.

The MIC94345-FYCS TR is a versatile, 5V, low-noise voltage regulator suitable for low-voltage digital and analog design applications, including portable and consumer electronics, personal computers and digital cameras. It can be used in multiple system configurations, including single-supply, multiple-supply and mixed-supply designs. A combination of low dropout voltage and wide input/output voltage range, together with high stability and current capability, makes it an ideal choice for a variety of low-voltage applications.

The core elements of the MIC94345-FYCS TR are its high-performance flux regulators. These flux regulators provide the necessary voltage regulation and transient response to ensure that the output voltage remains within the specified tolerance. The output voltage is dependent on the reference voltage of the device, which is adjustable via the output voltage selection pin (VOSEL). A single resistor can be used to set the output voltage to any value from 0.7V to 4.2V. The MIC94345-FYCS TR has built-in overcurrent protection for overcurrent conditions, as well as a power-on reset circuit for increased reliability.

The MIC94345-FYCS TR is also equipped with an error flag pin (E/F) for overcurrent and overvoltage conditions, as well as an enable pin (EN) for remote activation. Additionally, the device features a power-good flag pin (P/G), which provides the user with an indication of whether the output voltage is within specification. This allows the user to monitor the output voltage in real-time, and adjust the output voltage when necessary.

The MIC94345-FYCS TR operates across a broad operating temperature range of -40°C to +125°C, making it suitable for use in many applications. It is also highly efficient, with a quiescent current of just 1mA and a low dropout voltage of 40mV, which results in high system efficiency, allowing a longer period of operation before battery replacement is required.

Overall, the MIC94345-FYCS TR is an ideal solution for low-voltage digital and analog design applications due to its wide operating temperature range, high output accuracy, fast transient response, low-noise operation and high current capability. It is also highly efficient, which makes it suitable for many power-efficient applications. The user can also monitor the output voltage in real-time, as well as enable and disable the device remotely.
