The MIC5200-4.8YS is designed to be a low-power adjustable linear voltage regulator. It is a part of the family of low-power adjustable linear regulators from Micrel (MICREL Incorporated). It is a 3-terminal voltage regulator with low dropout voltage (LDO). The MIC5200-4.8YS offers excellent line and load transient response and is capable of providing up to 4.8A of output current.

The MIC5200-4.8YS is suitable for applications in portable electronics, such as notebook computers, digital cameras, cell phones and PDAs. It provides excellent power supply regulation for applications that require high efficiency, small size and low-power consumption. It is also suitable for non-PC applications such as automotive, industrial, and medical systems.

The MIC5200-4.8YS allows input voltages between 3V and 20V, while the output voltage is adjustable from 1.235V to 20V making the device suitable for a wide range of applications. The device features integrated protection against reverse current, short circuit, and over temperature. This component is available in SOT-223 and TDFN-8L packages.

The MIC5200-4.8YS features a high-speed Active Pulse Frequency Modulation (PFM) control loop. This feature enables the device to regulate the output voltage precisely over a wide range of load currents and input voltages. The device also includes a Soft-Start feature which limits the inrush current at turn-on.

The MIC5200-4.8YS is designed to minimize power consumption. The device utilizes a Power Platform Controller (PPC) to regulate the power consumption of the device. The PPC is an algorithm which actively predicts the current drawn by the device based on the load demand. The result is a low noise regulator with less than 1µA of quiescent current.

The MIC5200-4.8YS also features a fast transient response time and low output voltage ripple. Its adjustable output voltage is regulated within ±2% of the target voltage even when subjected to heavy load transients. The device also features a Thermal Foldback function, which limits the output current in the event of an over-temperature condition.

The MIC5200-4.8YS is an excellent choice for applications requiring high-efficiency, small size, and low-power consumption. The device is offered in an SOT-223 and TDFN-8L package. Its precise output voltage regulation, thermal protection, high-speed performance, and low quiescent current capabilities make it suitable for a wide range of applications.
