LD2982AM33R Description

Short technical summary and product information.

The STMicroelectronics LD2982AM33R is a linear voltage regulator designed for efficient power management. It offers a stable, fixed output voltage of 3.3V and can supply up to 50mA of current. This device is suitable for applications requiring a reliable voltage source.

 

Key electrical characteristics include a maximum input voltage of 16V and a typical voltage dropout of 0.225V at 50mA. The regulator also features a Power Supply Rejection Ratio (PSRR) of 45dB at 1kHz, indicating its ability to filter out noise from the input supply. Protection features such as over current and over temperature shutdown are integrated to safeguard the device and the connected circuitry.

 

The LD2982AM33R operates within a temperature range of -40°C to 125°C. It is supplied in a compact SOT-23-5 (SC-74A, SOT-753) surface-mount package, making it ideal for space-constrained designs. The 'Enable' control feature allows for easy power management in system designs.
