The STMicroelectronics LF25ABDT is a low dropout linear voltage regulator designed for various applications. It provides a fixed output voltage of 2.5V and can supply up to 500mA of current.
Key electrical characteristics include a very low dropout voltage of 0.45V and a typical quiescent current of 50 µA in OFF mode and 500 µA in ON mode. The regulator features internal current and thermal limit protection, along with a PSRR of 82dB to 65dB across a frequency range of 120Hz to 10kHz.
This series is suitable for low noise, low power applications, especially in battery-powered systems. The LF00 series, including the LF25ABDT, is available in multiple package types, with this specific part in a DPAK (TO-252) surface mount package. It requires only a 2.2 µF capacitor for stability, allowing for space and cost savings in designs.
The operating temperature range is -40°C to 125°C, making it suitable for demanding environments. The device offers logic-controlled electronic shutdown and is available with output voltage tolerances of ±1% or ±2% at 25°C.
