LD39050PU25R is a series of Negative Linear Voltage Regulators from ON Semiconductor, designed for applications that require low output voltage, high current and small size. It is ideal for providing a regulated negative supply for the data converters, transistors and logic circuits used in consumer electronics and communications systems. The LD39050PU25R is a 3-terminal negative linear regulator with a 12 amp output current capability. It offers an adjustable output voltage that can be adjusted between -5v and -25v, and it offers an adjustable output down to 1.225v. It is available in industry-standard, convenient-to-solder, TO-220 and TO-263 packages. The LD39050PU25R is ideal for applications that require low output voltage and high current. It is well suited to applications such as providing a constant regulated negative voltage for the LDO’s and regulators, and for providing regulated negative voltages to transistors and logic circuits used in consumer electronics and communications systems. The LD39050PU25R features a Drop Out Voltage (DOV) that is low enough for it to remain in regulation even under high current load conditions. This allows the LD39050PU25R to maintain a precise output voltage until the drop out voltage is reached which keeps the output voltage stable. The low drop out voltage also helps to extend the life and stability of the voltage regulator. The LD39050PU25R includes several safety features such as over temperature protection, current limitation and protection against reverse battery installation. The current limiting protects against overload and ensures that regulator remains running without damaging the regulator or the load. The reverse battery protection helps to protect the device and the circuit that it is connected to if the power supplies are connected in the wrong order. The LD39050PU25R is designed for use in an adjustable voltage-mode regulator. It is capable of supplying up to 12 amps of regulated negative current. It has resistor divider at the output node to adjust the output voltage. The input voltage can be from -6v to -2Ov and the maximum output voltage is -25V. It also has an internal current limiting feature and thermal protection. The maximum junction temperature is 150°C. In conclusion, the LD39050PU25R is a low output voltage, high current, 3-terminal negative linear voltage regulator. It is ideal for providing a regulated negative supply for the data converters, transistors and logic circuits used in consumer electronics and communications systems. The LD39050PU25R includes safety features such as over temperature protection, current limiting, and protection against reverse battery installation. The low drop out voltage keeps the output voltage stable and helps to extend the life and stability of the voltage regulator.
