The MIC2951-02YM-TR is a two-output linear voltage regulator designed specifically to power SRAM, microprocessors, and logic circuits. This device is designed specifically to reliably provide power to a wide range of 3V to 3.6V power applications. The MIC2951-02YM-TR features a low-current input circuit, low quiescent current, and an adjustable current limit.

Features

• Input voltage range: 4V to 16V
• Output voltage: 3V to 3.6V (adjustable)
• Output current: up to 1A
• Fixed 500mA output current limit
• Low dropout voltage

Application Fields

The MIC2951-02YM-TR is primarily used in high-performance processor, SRAM, and logic circuits that require reliable and constant power. Examples of application fields that may benefit from its use are servers, storage systems, consumer electronics, and embedded devices.

Working Principle

The MIC2951-02YM-TR operates on a linear regulator principle. The device uses the voltage drop between the input and the output to determine a set current that is then fed through the output. This current is monitored and is kept constant through the use of feedback within the device. As the load on the output varies, the MIC2951-02YM-TR will adjust the output current to maintain a constant output voltage.

The MIC2951-02YM-TR is designed with a fast response time and a low dropout voltage of less than 400mV at 1A. This allows the device to react quickly to changes in the load while maintaining the output voltage within a tight range.

The MIC2951-02YM-TR also features adjustable current limit protection that is designed to protect against potentially damaging overcurrent events. The adjustable current limit can be adjusted from 250mA to 1A and is designed to protect the device and its components in the event of a short circuit or overload.

Conclusion

The MIC2951-02YM-TR is a versatile, reliable, and cost-effective power management solution that is ideal for powering a wide variety of 3V to 3.6V applications. This device offers a low-current input circuit, low quiescent current, fast response time, and adjustable current limit protection, making it a great choice for powering SRAM, microprocessors, and logic circuits.
