LDLN025M18R Description

Short technical summary and product information.

The LDLN025M18R from STMicroelectronics is a linear voltage regulator designed for efficient power management. It delivers a stable 1.8V output voltage with a maximum output current of 250mA. The device operates with a low quiescent current of 25 µA, making it suitable for power-sensitive applications.

 

Key electrical characteristics include a maximum input voltage of 5.5V and a low voltage dropout of 0.2V at 250mA. The regulator also offers features such as Enable control and protection against over-current, over-temperature, and short circuits. Its PSRR performance ranges from 80dB to 60dB across a frequency range of 100Hz to 100KHz.

 

Designed for surface mount applications, the LDLN025M18R is supplied in a SOT-23-5 package (also referred to as SC-74A, SOT-753). The operating temperature range is -40°C to 125°C (TJ), ensuring reliable performance in various environmental conditions. This component is ideal for use in portable electronics, battery-powered devices, and other applications requiring a compact and efficient voltage regulation solution.
