MIC5209-2.5BS TR is a linear voltage regulator from the MIC5200 family of regulators from Micrel. The regulator provides up to 500mA of continuous output current with an output voltage of 2.5V. It is designed to be used in a variety of applications, from power management to portable devices and embedded systems.

The MIC5209-2.5BS TR utilizes advanced bipolar linear regulation topologies for a low dropout voltage performance. The regulator features a low noise, low thermal resistance and stable operation. Additionally, the device’s wide operating temperature range makes it suitable for use in a broad range of industrial and automotive applications.

The device’s working principle is based on the voltage regulator topology. This makes use of a voltage reference, error amplifier and a series pass element, to provide a regulated output without any changes to the input current. The error amplifier monitors the output voltage and compares it to a reference. If the monitored voltage falls below the reference, the error amplifier will pulse the gate of the series pass element to bring it back up to the reference. The series pass element is also responsible for controlling the output voltage as it is connected in series with the output load.

The MIC5209-2.5BS TR operates over an extended input voltage range of 2.7V to 5.5V, providing it with superior load and line regulation characteristics compared to other devices in the same family. It also has a fast transient response and is capable of sustaining high surge currents when needed. The device also features foldback current limiting protection to reduce the short circuits current, offering better operational safety.

The MIC5209-2.5BS TR also features an enable pin, which allows the IC to be turned on or off using a logic signal or a transceiver. This makes the device suitable for use in applications such as low power systems, where the device can be used in a power-saving mode. Also, the device supports soft start and overvoltage protection features, providing improved reliability and safety.

The MIC5209-2.5BS TR is suitable for a wide range of uses in applications such as LED lighting, RF transmitters, DC-DC converters, industrial automation and motor controllers. The device also integrates well with other ICs, allowing easy integration into a variety of systems. With its robust design, low quiescent current and high resistance to short circuits, the MIC5209-2.5BS TR is a reliable and efficient linear voltage regulator.
