The NJM78L02A is a two terminal low dropout adjustable series voltage regulator, suitable for use in systems with limited power resources, requiring low noise and low power consumption. It is a very useful device for setting and regulating electrical power supplies. The NJM78L02A can be easily used in a variety of applications including powering sensors, powering microprocessors and providing output voltage regulation for power modules.

The NJM78L02A is a linear regulator, meaning that it uses the same fundamental principle as a resistor divider. The device is designed to ensure a stable and reliable output voltage regardless of variations in input voltage and loading conditions. The NJM78L02A uses a PNP transistor, a zener diode and resistors to create a feedback voltage that is proportional to the output voltage. The resulting feedback voltage is compared to the reference voltage inside the device and the output voltage is controlled accordingly.

The NJM78L02A is configured with a minimum input voltage of 2.7V and an output voltage range of 1.8V to 15V. The maximum input voltage of the device is 20V. The power dissipation of the device can reach up to 3.2 W over a wide temperature range. In addition, the device has a wide operating temperature range of -40°C to 125°C.

The NJM78L02A is capable of driving 1A output current and is capable of supplying a minimum output current of 100mA at low input voltage, making it ideal for applications such as powering microprocessors, providing output voltage regulation for power modules, and many others. Furthermore, the device has a low thermal resistance which eliminates the need for external heat sinks.

In summary, the NJM78L02A is a two terminal adjustable low dropout series linear voltage regulator with a wide range of application possibilities. It features an input voltage range of 2.7V to 20V, output voltage range from 1.8V to 15V, 1A output current, and maximum power dissipation of 3.2W. Its excellent temperature performance, wide operating temperature range, and low thermal resistance make the NJM78L02A an ideal device for a wide range of applications.
