LDK130M33R Description

Short technical summary and product information.

The STMicroelectronics LDK130M33R is a linear voltage regulator designed for efficient power management. It delivers a stable 3.3V output voltage with a maximum current capability of 300mA. The device features a low dropout voltage of 0.4V at 300mA, making it suitable for applications where power efficiency is critical.

 

Key electrical characteristics include a quiescent current of 60µA and a Power Supply Rejection Ratio (PSRR) of 55dB at 120Hz to 10kHz. Protection features such as over current and over temperature are integrated to ensure device reliability and system safety. The regulator operates over a temperature range of -40°C to 125°C (TJ).

 

This component is supplied in a SOT-23-5 (SC-74A, SOT-753) surface-mount package, facilitating integration into compact electronic designs. Its fixed output and enable control feature make it a straightforward solution for various power supply applications.
