MIC5256-2.6BM5

MIC5256-2.6BM5 Description

The MIC5256-2.6BM5 is a high-performance linear regulator designed by Micrel Inc., a leading manufacturer in the power management integrated circuits (PMIC) space. This device is specifically tailored for applications requiring a fixed output voltage of 2.6V, ensuring stable power supply with minimal voltage fluctuations. With a maximum input voltage of 6V and a maximum output current of 150mA, the MIC5256-2.6BM5 is well-suited for a variety of low-power, high-efficiency applications.

The regulator features a low dropout voltage of 0.25V at 150mA, which allows it to maintain regulation even when the input voltage is close to the output voltage. This is particularly beneficial in battery-powered devices where the input voltage may drop as the battery discharges. The quiescent current of only 150 µA ensures minimal power consumption during operation, making it ideal for portable and battery-operated devices.

The MIC5256-2.6BM5 also includes several protection features such as over-current protection, over-temperature protection, and under-voltage lockout (UVLO), which safeguard the device and the connected circuitry from potential damage. Additionally, the regulator offers a power supply rejection ratio (PSRR) of 60dB to 45dB across a frequency range of 10Hz to 10kHz, ensuring high performance in noisy environments.
