Microchip Technology SR087SGG Adjustable Switching Regulator
The SR087SG-G is an adjustable, offline inductorless switching regulator designed to operate directly from a rectified AC line. It turns a pass transistor on when the rectified AC voltage is below the desired output voltage and turns it off when the output reaches a set level. The device includes a linear regulator providing a fixed 5V output, suitable for low-power applications. It offers efficient operation without magnetic components, no high-voltage capacitors, and features a built-in soft start. The regulator supports up to 100mA combined output current and includes a logic-level enable input for easy control. Its design accommodates both 120V and 230V AC lines with minimal standby power consumption, making it suitable for consumer electronics and lighting applications.
