It has a wide input voltage range of 3V–18V and low no-load Consumption of 30μA, making it suitable even for battery-operated systems.

NJM78LR05BD# provides adjustable output voltage in the range of 0.8V–14V and is ideal for low-power applications such as microprocessors and DSPs. It features a POR (Power-On-Reset) function and temperature protection circuit for safety operation. The small size of 8-pin SOP makes it ideal for use in portable electronic devices.

Working Principle of NJM78LR05BD#

NJM78LR05BD# is a CMOS voltage regulator, which works mainly by comparing the output voltage with a reference voltage. When the output voltage is too high, the reference voltage is higher than the output voltage and the output transistor is turned off. On the contrary, when the output voltage is too low, the reference voltage is lower than the output voltage and the output transistor is turned on. The output of the regulator is controlled to match the reference voltage by this process. NJM78LR05BD# is a common-mode voltage regulator, meaning that both the input voltage and the output voltage from the regulator are compared to the reference voltage.

NJM78LR05BD# has an adjustable current source and an adjustable voltage reference source. This makes it possible to adjust the output voltage to a precise value. The adjustable current source consists of metal-oxide-semiconductor transistors (MOSFETs), which act as a switch. The adjustable voltage reference source contains a voltage reference diode, which acts as the reference voltage.
