The MIC2950-05BZ is a linear voltage regulator from Micrel, known for its power semiconductor products. This regulator operates from an input voltage between 4.5 V and 15 V and provides a regulated output voltage of 5 V. It features a power save mode, allowing it switch to a lower quiescent current for increased efficiency when the output current is low, and it comes in a thermally-enhanced 8-lead MSOP package.
MIC2950-05BZ Application Field
The MIC2950-05BZ is typically used as a core voltage regulator on main boards, hard drives and other electrical devices with low power and high precision requirements. It is well-suited for microcontroller, FPGA and ASIC applications and can be used in a wide range of settings. It supports both surface mount and through-hole designs, which allows it to easily fit into existing designs. Its low-dropout (LDO) design also means that it stays very efficient while regulating voltage over a wide current range.
MIC2950-05BZ Working Principle
The MIC2950-05BZ linear voltage regulator works by allowing a small current to flow from its input to its output. This current will have a proportional effect on the output voltage, thus keeping its output voltage at a pre-defined level. This is achieved through a feedback network, which monitors the voltage at the output and adjusts the regulator’s internal current accordingly. To ensure that the MIC2950-05BZ is always working correctly, it requires sufficient input and output capacitors for stability.
The MIC2950-05BZ features a power save mode, which allows it to switch to a lower quiescent current when the output current is low. This power save mode can be enabled or disabled through the use of a control pin, allowing the user to determine when the regulator should enter its low power mode. The MIC2950-05BZ also features excellent thermal performance, with a maximum junction temperature of 125°C, allowing it to operate reliably even in challenging conditions.
Conclusion
The MIC2950-05BZ from Micrel is a linear voltage regulator capable of providing an accurate 5 V regulated output voltage from an input voltage between 4.5 V and 15 V. It is designed primarily for use in main boards, hard drives, microcontrollers, FPGAs and ASICs, but can be used in a wide range of applications. It has excellent thermal performance and a low-dropout design to ensure maximum efficiency. Its power save mode further enhances its efficiency when the output current is low, making it an ideal choice for many applications.
