Linear voltage regulators, or linear regulators, are integrated circuits (ICs) used to maintain a constant voltage at the output regardless of changes in the input voltage and other loads. The AN8009 is a linear voltage regulator IC from Anachip Corporation that provides fixed output voltage ranging from 0.8V to 17V. This article will focus on the application field and working principle of the AN8009 Linear Voltage Regulator.

Application Areas of AN8009

The AN8009 is highly suitable for low noise, low dropout linear regulator applications. It can be used in computer peripheral equipment, LCD displays, LED displays, and other consumer electronics such as telephone sets, smart phones, digital cameras, portable medical equipment and measurement instruments. The device is also suitable for power management in low noise, low quiescent current applications where high efficiency is needed.

Working Principle of AN8009

The AN8009 is based on a modified “Constant Output” architecture and operates with a supply voltage range from 1V to 16V. The device produces a constant output voltage between 0.8V and 17V with an adjustable current limit of up to 1.5A. The device features an improved output voltage error (OVE) of 0.1%. The device includes thermal shutdown protection and also includes a power-saving feature that reduces quiescent current when the load current falls below 10mA.

The AN8009 enables a 45μA quiescent current in its standby mode. The input voltage range is from 1V to 16V and the quiescent current is well below 1mA. The operating temperature range is from -40°C to +85°C. The device also features a low output voltage ripple and low noise characteristics.The device also has a fast turn-off time and low dropout characteristics.

Advantages of AN8009

The AN8009 is an ideal solution for low noise, low dropout linear regulator needs. It has a wide operating supply voltage range and is capable of stable performance up to 16V. It also has low output voltage ripple and low noise characteristics. With a power saving feature that reduces quiescent current when the load current falls below 10mA, the device provides high efficiency operation and low power consumption. The device also has a fast turn-off time and low dropout characteristics.All these features make the AN8009 an ideal choice for low noise, low dropout linear regulator applications.
