Linear voltage regulators are essential components of modern electronic device designs due to their reliability, low cost and minimal power dissipation. TG7805AK-883B is a current-limited, fixed-voltage Regulator designed to provide a highly accurate five volts output. It requires only two external components, making it ideal for most applications where space is at a premium. This application note provides a detailed description of the features of the TG7805AK-883B, how it works and how it can be used in a variety of applications.

The TG7805AK-883B is a low dropout, high-efficiency, 5V limiter-regulator that has a dropout voltage of just 100mV. The Regulator is based on the TO-260 package and is optimized for low voltage and low current applications. The TG7805AK-883B incorporates an advanced overload protection system, consisting of over-temperature, over-current limit and a thermal shutdown circuit that is triggered by an over-temperature condition. This protection system is especially useful for applications requiring low power consumption, high efficiency and a stable output voltage. The Regulator can be used in a variety of systems, including DC-DC converters, battery-powered devices, automotive applications, and computer systems.

The TG7805AK-883B features a high output current capability (600mA) with very low dropout and low temperature characteristics. The Regulator has a low quiescent current (1µA) and can operate at a wide input voltage range of 2V to 25V. It also features a low minimum operating voltage and can be used with batteries. The Regulator has an over-temperature protection circuit which will shut down the Regulator in the event of an over-temperature condition. The Regulator also includes both open loop and short circuit protection.

The TG7805AK-883B works by using a reference voltage to control the output voltage. The reference voltage is set with an internal bandgap circuit and is maintained by a voltage divider connected to the output of the Regulator. The output voltage is controlled by a series of transistors connected in an NPN configuration. When the output voltage reaches the desired level, the transistors start to limit the current to the output of the Regulator. As the input voltage drops, the output current is reduced, resulting in a stable output voltage. This type of circuit is known as a current-limiting linear regulator.

The TG7805AK-883B is ideal for a variety of applications, including DC-DC converters, battery-powered devices, automotive applications, and computer systems. In addition, the Regulator can be used to power a wide range of circuits, including micro controllers, op amps, power transistors, MOSFETs, IGBTs, and solenoid actuators. The Regulator’s small size and high output current capability make it an ideal choice for applications that require low power consumption and high efficiency.

The TG7805AK-883B is a high-efficiency, low noise, low dropout, current limiting linear Regulator. The Regulator provides a stable five volt output and requires only two external components, making it ideal for space-constrained applications. It features a low quiescent current, a wide input voltage range, and an over-temperature protection circuit. The Regulator is suitable for a wide range of applications, including DC-DC converters, battery-powered devices, automotive applications, and computer systems.
