NJM79L08L2A Application Field and Working Principle

NJM79L08L2A is a low-dropout (LDO) linear regulator widely used in power management integrated circuits (PMIC) which targets low voltaged applications, particularly mobile or handheld devices. The device supports highly stable voltage output with a low current consumption of 1.3 mA, making it one of the most efficient voltage regulators available.

NJM79L08L2A, being a LDO linear regulator, functions based on the principle of linear regulation. It is a regulating device whose output voltage is independently governed by its input voltage by maintaining the ratio of output to input at a constant value. The output voltage is produced with a linear function of the input voltage, thus it is called linear regulation.

In order to regulate the output voltage of NJM79L08L2A, a difference between input and output voltage must be kept as low as possible, which is referred to as the dropout voltage. The dropout voltage is usually determined by the gate voltage of the device. As the gate voltage increases, the dropout voltage decreases and therefore the device becomes more efficient. The dropout voltage of NJM79L08L2A is typically 0.1V and its input voltage range is 2.5V to 6.0V.

NJM79L08L2A is widely used in portable electronics, handheld or automotive applications, due to its small size, high voltage stability and low-voltage characteristics. It can supply a regulated output voltage of up to 5.0V with a current up to 100mA. Its operating temperature ranges from -40 degree Celsius to +85 degree Celsius and can withstand a wide range of extreme temperatures, thus making it suitable for use in environments with drastic changes in temperature.

In addition to its low dropout voltage characteristics, NJM79L08L2A has several other features that make it suitable for PMIC applications, such as over current protection (OCP), power good regulation (PGR), thermal shutdown (TSD), and current limit protection (CLP). These features can protect the device from being damaged by current overload, voltage overshoot, and temperature extremes.

NJM79L08L2A is a reliable and efficient power management solution with small size, low power consumption and excellent thermal stability, which makes it ideal for maintaining a stable power supply in a variety of PMIC applications. It is particularly suitable for low voltage applications, such as those found in mobile or handheld devices, and its superior performance and efficiency make it the preferred choice for a variety of power management applications.
