LDK120DM33R Description

Short technical summary and product information.

The STMicroelectronics LDK120DM33R is a linear voltage regulator with a fixed 3.3V output. It is designed to operate with an input voltage up to 5.5V and can supply a continuous output current of 200mA. The device features a low quiescent current of 60 µA, making it suitable for power-sensitive applications.

 

Key electrical characteristics include a voltage dropout of 0.3V at 200mA and a Power Supply Ripple Rejection (PSRR) of 55dB at 120Hz to 10kHz. Protection features such as over current and over temperature shutdown are integrated to enhance reliability. The regulator also includes an enable control feature.

 

This component is supplied in a SOT-23-5 surface-mount package, also referred to as SC-74A or SOT-753. Its operating temperature range is from -40°C to 125°C (TJ), making it suitable for a variety of environmental conditions. The LDK120DM33R is a single-output positive voltage regulator.
