LDK120C28R Description

Short technical summary and product information.

The STMicroelectronics LDK120C28R is a fixed output linear voltage regulator designed for efficient power management. It provides a stable 2.8V output voltage with a maximum output current of 200mA. The device features a low voltage dropout of 0.3V at 200mA, making it suitable for battery-powered applications where voltage efficiency is critical.

 

Key electrical characteristics include a PSRR of 55dB at 120Hz to 10kHz, indicating good noise filtering capabilities. Protection features such as over current and over temperature shutdown are integrated to ensure device reliability and system safety. The regulator operates over a wide temperature range of -40°C to 125°C.

 

This component is supplied in a compact SOT-323-5 surface-mount package, ideal for space-constrained designs. The 'Enable' control feature allows for easy power sequencing and management. Its fixed positive output configuration and robust protection make it a versatile choice for various electronic circuits requiring a reliable 2.8V supply.
