AP7315D-28W5-7 is a linear adjustable voltage regulator developed and produced by Airoha Technology Corporation. It was first introduced in 1998 and has since become one of the most popular voltage regulators in the industry. The device is an adjustable three-terminal negative voltage regulator with a voltage range of -8V to -22V and a maximum regulated output current of 1.5A. It is ideal for use in a variety of applications such as low-power electronic circuit design, power supply design, and load-sharing applications.

The AP7315D-28W5-7 is constructed with a 0.5Ω fuse as its main protection feature. This 0.5Ω fuse is capable of providing over-current protection, short circuit protection, and over-voltage protection. It also has built-in transient protection to prevent over-voltage when the sudden load becomes larger. The device has a high current good temperature coefficient and low voltage drop, making it highly reliable.

It uses a voltage divider principle to regulate the output voltage. An external resistor sets the output voltage to almost any voltage from -8V to -22V. This voltage divider is also used to sense the output voltage and adjust it to the required value. The current flowing through the resistor follows the equation for a linear relationship.

It has a wide output voltage range, low voltage drop and a low quiescent current. The device is able to provide a stable output voltage without significant temperature variation. It also has a very low output voltage ripple and low output noise. In addition, it has a low phase-delay over temperature, making it a good choice for high switching frequency applications. The device has an operating temperature range of -40°C to +125°C.

The AP7315D-28W5-7 has an adjustable current limit, protection against output short circuit, and protection against output over-voltage. It also has a thermal protection feature which starts the device with a low power rating to prevent it from overheating and causing damage. The device offers excellent protection against transient disturbances and can be used to minimize the effects of power surges and line noise.

The AP7315D-28W5-7 is a great choice for low-power linear adjustable voltage regulator applications. It has a low quiescent current and a low voltage drop making it efficient. It also allows for precise voltage setting, excellent protection against power surges and line noise, and high accuracy over temperature. It is a cost-effective and reliable solution for a range of applications.
