LDK120M08R Description

Short technical summary and product information.

The LDK120M08R from STMicroelectronics is a linear voltage regulator IC designed for power management applications. It provides a fixed output voltage of 0.8V and can supply up to 200mA of current. The device operates within a wide temperature range of -40°C to 125°C, making it suitable for various environmental conditions.

 

Key electrical characteristics include a maximum input voltage of 5.5V, a low dropout voltage of 0.3V at 200mA, and a quiescent current of 60 µA. Protection features such as over-current and over-temperature protection are integrated for enhanced reliability. The regulator also offers a PSRR of 55dB at 120Hz to 10kHz.

 

This component is housed in a SOT-23-5 package, designed for surface mounting. Its positive output configuration and enable control feature make it a versatile choice for designs requiring stable voltage regulation. The package type SC-74A, SOT-753 is also associated with this part.

 

The LDK120M08R is suitable for applications requiring a stable, low-voltage power supply. Its compact size and surface-mount capability facilitate integration into space-constrained electronic devices.
