NJM2845DL1-25-TE1# is a step-down DC-DC voltage regulator, belonging toa linear voltage regulator. As a linear voltage regulator, it operatesaccording to the principle of series voltage regulation. When thisregulation method is used, a steady DC output voltage is obtained evenunder input voltage changes and load changes; meanwhile, the constantoutput voltage is obtained by the feedback control loop and linearregulator stabilizing circuits.

NJM2845DL1-25-TE1# is an adjustable voltage regulator that provides anoutput voltage of 1.25V. The range of the output voltage is adjustablefrom 1.0V to 1.5V to meet different applications. It operates over avoltage range of 2V-18V based on a 450mA load current and can support up to 800mA load current. The operating frequency of the device ranges from200kHz to 2.2MHz, with a user-selectable synchronous rectifiedefficiency boosting mode.

The device features an internal softstart circuit, allowing for longerstartup time and reduced ripple for applications that require a slowstartup. Additionally, the device includes a substantially low quiescentcurrent of 2mA, helping to save system power on battery-poweredapplications.

NJM2845DL1-25-TE1# includes built-in current protection, overcurrentprotection, thermal protection and UVLO, providing a high level ofprotection for the device. The device is RoHS compliant and can operateacross a wide temperature range of -40 C to 125 C.

NJM2845DL1-25-TE1# is suitable for a wide range of applications such assmart phones, displays, monitors, tablets, and portable DVD players. Itcan be used to provide stable power supply for digital products, serialport products, data acquisition systems and automation systems.

In conclusion, NJM2845DL1-25-TE1# is an ideal linear voltage regulatorfor portable electronic devices due to its adjustable concentration,high efficiency, low quiescent current, wide operating frequency rangeand excellent protection features.
