The KF25BD-TR with LDO Voltage Regulators 2.5V 0.5A Positive manufactured by STMicroelectronics is a low-dropout (LDO) voltage regulator that provides an output current of 0.5 amps and a voltage of 2.5 volts. It is designed for use in mixed-signal, digital and RF applications. Its tight line and load regulation make it ideal for powering analog and digital circuits. Its low dropout voltage of only 150mV (at full load) ensures the highest efficiency, while its wide input voltage range of 1.5V up to 24V ensures stability at different voltage levels. It also has overcurrent, overtemperature and reverse current protection, making it a reliable choice for various applications.
