• Overcurrent protection
• Overtemperature protection
• Short circuit protection
• Small SOT-25 package

Benefits:

• Stable and accurate 3.3V power supply
• Extended battery life due to low quiescent current
• Protection against overcurrent, overtemperature and short circuits
• Simplified circuit design
• Small footprint for space-constrained applications

Additional Details:

The NJM2846DL3-33 features a low dropout voltage, which allows it to maintain a stable 3.3V output even when the input voltage is only slightly higher than 3.3V. This is important in battery-powered devices where the battery voltage decreases as it discharges. The low quiescent current minimizes power consumption, further extending battery life.

The regulator also incorporates built-in protection features, including overcurrent protection, which limits the output current in the event of an overload; overtemperature protection, which shuts down the regulator if it overheats; and short circuit protection, which protects the regulator from damage if the output is shorted to ground. These features enhance the reliability and robustness of the power supply.

The NJM2846DL3-33 is available in a small SOT-25 package, which makes it ideal for use in space-constrained applications. It is a simple and cost-effective solution for providing a regulated 3.3V power supply in a wide range of electronic devices.
