The AN79L10M is the type of voltage regulator that falls under the PMIC-Voltage Regulators-Linear category. It is a low-dropout and low-power three-terminal voltage regulator. The AN79L10M has been especially designed for primary li-ion battery applications. This part operates using a fixed 10A supply, and comes with an advanced design optimization technology. Its strength lies in its ability to provide voltage regulation even under extreme operating conditions. This paper outlines the application field and working principle of AN79L10M.

The AN79L10M is a popular choice for all Li-ion battery powered applications due to its impressive performance and low power consumption. This part is designed for generating stable, precise and ripple-free 1.5V to 8.5V power supply. It offers overload protection and low drop-out voltage, making it an ideal choice for applications with very tight requirements, such as digital media players, mobile phones and portable gaming devices. The AN79L10M also features a low quiescent current, which makes it an energy-efficient option compared to other voltage regulators.

The working of the AN79L10M is meant to give its users an efficient and reliable output power under challenging conditions. It features an active high-side current limiter, which helps in controlling the output current level, thus avoiding current surges and over-voltage conditions. In addition, its over-temperature protection helps in avoiding thermal runaway. Furthermore, the on-chip thermal shutdown circuitry helps protect the IC from thermal overloads. This regulator also provides maximum power stability of up to 8.5V with a supply voltage of 10V.

In the AN79L10M, the output voltage is set by the voltage setting resistor. If a large change in output voltage is desired, the voltage setting resistor can be adjusted accordingly. The selection of the resistor also helps in controlling the output ripple, transient response and overshoot. In addition, the internal band gap voltage reference ensures precise output voltage. The reference voltage is then compared with the output through an error amplifier, and the output voltage is adjusted accordingly.

The AN79L10M also has a built in thermal shutdown circuitry which shuts down the regulator when it becomes too hot. This helps to protect the part from overheating caused by prolonged operation at high current levels. The part also has an active low-side current limiter, which limits the output current to a constant level, avoiding current spikes. When the output current reaches the current limit set by the resistor, the limiter turns off and the output current is limited.

The AN79L10M is suitable for a wide range of applications, such as digital media players, mobile phones, gaming devices, laptop computers and medical equipment. Its impressive performance and low power consumption make it an attractive choice for battery powered applications. In addition, its active high-side current limiter and over-temperature protection make it suitable for challenging operating conditions. This voltage regulator can provide precise and stable output power under demanding conditions and is an attractive choice for battery powered applications.
