The MIC5209-3.3YS is an IC component designed by Micrel Inc. It is a low dropout (LDO) voltage regulator that provides a fixed 3.3V output voltage with a maximum output current of 150mA. The IC is suitable for various applications such as portable devices, battery-powered systems, and embedded systems.
One of the key features of the MIC5209-3.3YS is its low dropout voltage, which is only 45mV at a 150mA load. This makes it suitable for applications where input voltages are close to the desired output voltage, ensuring efficient power delivery and reducing power dissipation. The low dropout voltage also allows it to operate with a wide input voltage range from 2.5V to 16V.
Another important feature is the excellent line and load regulation provided by the MIC5209-3.3YS. It offers a line regulation of 0.04% per volt and a load regulation of 0.1% per mA. These characteristics make it suitable for applications where a stable output voltage is required, even in the presence of varying input voltages or load currents.
The MIC5209-3.3YS also incorporates thermal shutdown and current limiting protection features. The thermal shutdown protection prevents the IC from overheating by shutting it down when the junction temperature exceeds a safe limit. The current limiting protection ensures that excessive current does not flow through the IC, protecting it from damage
