LDK120M12R Description

Short technical summary and product information.

The STMicroelectronics LDK120M12R is a linear voltage regulator designed for efficient power management. It offers a stable 1.2V fixed output voltage and can supply a maximum current of 200mA. The device features a low voltage dropout of 0.3V at 200mA, making it suitable for applications where power efficiency is critical.

With an input voltage range up to 5.5V, the LDK120M12R is versatile for various power supply designs. It includes essential protection features such as over-current and over-temperature protection, enhancing system reliability. The regulator operates across a wide temperature range from -40°C to 125°C.

Packaged in the SOT-23-5 surface-mount case, this component is ideal for space-constrained applications. Its linear regulation architecture ensures low output noise, beneficial for sensitive electronic circuits. The enable control feature allows for power sequencing and shutdown capabilities.

Key electrical characteristics include a quiescent current of 60 µA and a supply current of 100 µA, contributing to low power consumption in standby modes. The Power Supply Rejection Ratio (PSRR) of 55dB at 120Hz to 10kHz indicates good performance in rejecting input voltage ripple.
