The NJM2878F3-25 is a 250mA low-dropout (LDO) voltage regulator manufactured by New Japan Radio (NJR). It's designed to provide a stable 2.5V output voltage from a wide range of input voltages. LDO regulators are known for their low quiescent current and ability to maintain a regulated output voltage even when the input voltage is close to the output voltage.

Applications

• Battery-powered devices
• Portable electronics
• Microcontroller power supplies
• Sensor power supplies
• Post-regulation for switching power supplies

Features

• Output Voltage: 2.5V
• Output Current: 250mA
• Low Dropout Voltage
• Low Quiescent Current
• Overcurrent Protection
• Thermal Shutdown Protection
• Small SOT-23-5 package

Benefits

• Provides a stable and accurate 2.5V output voltage.
• Extends battery life due to its low quiescent current.
• Protects the regulator and the load from overcurrent and thermal overload conditions.
• Small package size enables compact circuit designs.
• Simple to use with minimal external components required.

Additional Details

The NJM2878F3-25 is designed for applications where a stable 2.5V supply is required with minimal power loss. The low dropout voltage allows the regulator to operate efficiently even when the input voltage is close to the output voltage. The overcurrent and thermal shutdown protection features enhance the reliability of the system. The SOT-23-5 package is compact and suitable for surface mount assembly. Consult the datasheet for detailed electrical characteristics, thermal resistance, and application circuit examples. External capacitors are typically required at the input and output for stability.
