St MicroElectronics Fixed LDO Voltage Regulator 3.3V 800mA DPAK-3

St MicroElectronics Fixed LDO Voltage Regulator provides a stable 3.3 V fixed output with a maximum output current of 800 mA, making it suitable for power management in circuits that require a regulated supply.

Overview

This low-dropout linear voltage regulator accepts an input voltage range of 4.75 V to 15 V. A typical dropout voltage of 1.1 V allows it to maintain regulation when the input is close to the output level, which can improve efficiency in portable devices. Internal current limiting and thermal shutdown help protect the regulator and the wider application under fault conditions.

Key Features

• Fixed 3.3 V DC output
• Maximum output current of 800 mA
• Typical dropout voltage of 1.1 V
• Typical supply voltage rejection of 75 dB, helping to minimise output ripple and noise from the input source
• Internal current limiting and thermal shutdown protection
• Surface-mount DPAK-3 (TO-252) package designed for PCB layout and heat dissipation
• Operating temperature range from -40 °C to 125 °C

Applications

Suitable for consumer electronics, embedded systems, telecommunications equipment, and automotive modules. The stated operating temperature range supports use in demanding industrial and automotive environments.

Choose the St MicroElectronics fixed LDO voltage regulator when a clean, regulated 3.3 V supply is required within a 4.75 V to 15 V input range.
