The LR8N3-G is a three-terminal, low-dropout linear voltage regulator that offers a multitude of features to meet the needs of many applications. It has a wide voltage and current range from 1.5V to 18V, and can provide up to 600 mA of output current, depending on the package size. The device has a built-in noise filter for improved regulation, as well as an enable pin for power savings in standby mode. The extended temperature range (-40°C to +85°C) makes it suitable for many industrial and automotive applications where wide temperature operation is necessary.

The main feature of the LR8N3-G regulator is its small size and low quiescent current. It is available in both TO-92 and SOT-23 packages, making it ideal for space-constrained applications such as handhelds and cell phones. The device requires a minimum input voltage of 1.8V, and its low dropout voltage (typically 151mV @ 600 mA) makes it an ideal choice for applications with limited headroom. The current limiting and thermal protection circuits provide protectioin to ensure safe and reliable operation.

The LR8N3-G can be used to generate a fixed output voltage in a wide range of applications. Typical uses include powering a microcontroller or memory, providing system power for mobile devices, and supplying voltage for audio amplifiers and motor control circuits. It can also be used for maintaining a specific output voltage in batteries or other power supply circuits.

The working principle of the LR8N3-G is based around its internal N-channel MOSFET. Its drain terminal is connected to the output pin, while its source is connected to the regulator’s own ground terminal. When the input voltage is higher than the output voltage, current flows through the MOSFET and into the regulated circuit. This current flow is controlled by varying the size and resistance of the MOSFET, enabling the regulator to maintain a constant output voltage. When the input voltage is lower than the regulated output voltage, the regulator shuts off, allowing no current to flow to the output.

Overall, the LR8N3-G is a versatile, low-dropout linear voltage regulator that can be used in a variety of applications requiring a regulated output voltage. Its small size, low quiescent current, and extended temperature range make it ideal for space-constrained, battery-powered, and automotive applications. Its operating principle is based on the internal N-channel MOSFET, allowing it to provide excellent performance and protection.
