Description

The ME1117 series of adjustable and fixed voltage regulators are designed to provide 1A output current and to operate down to 1A input-to-output differential. The dropout voltage of the device is guaranteed maximum 1.3V at maximum output current, decreasing at lower load currents.

On-Chip trimming adjusts the reference voltage to 1%. Current limit is also trimmed, minimizing the stress under overload conditions on both the regulator and power source circuitry.

Description

The STR-G8656 is specifically designed to satisfy the requirements for increased integration and reliability in off-line quasi-resonant flyback converters. This device incorporates the primary control and drive circuit with a discrete avalanche-rated power MOSFET. Power Switch Regulator for CRT TVs and Monitors.

A switching regulator, also known as a switch-mode power supply, is a type of voltage regulator that uses a switching element, such as a transistor, to regulate the output voltage. Unlike linear regulators, which adjust the output voltage by using a resistive element to drop the excess voltage, switching regulators work by rapidly switching the input voltage on and off to produce a regulated output voltage.

Switching regulators are typically more efficient than linear regulators, as they can handle larger voltage changes with less power loss. They are also more compact and lighter, making them ideal for use in portable electronic devices. Additionally, switching regulators are capable of regulating a wider range of voltage levels and can handle higher current loads.
