Linear Technology LT1507IS8-3.3 Voltage Regulator

The LT1507IS8-3.3 from Linear Technology is a high-performance step-down switching regulator designed to provide a fixed output voltage of 3.3V. This component is encased in a compact SO-8 package, making it suitable for space-constrained applications. Its ability to convert input voltages ranging from 4.5V to 60V to a stable 3.3V output makes it an ideal choice for a wide array of electronic devices, including portable equipment, embedded systems, and industrial controls.

With its high efficiency, the LT1507IS8-3.3 can deliver up to 1.5A of continuous output current, which ensures reliable performance even under heavy load conditions. The device features a switching frequency of 500kHz, which allows for the use of small, low-cost inductors and capacitors, thereby reducing the overall size and cost of the power supply design.

The LT1507IS8-3.3 incorporates several protection features to ensure the longevity and reliability of the application it powers. It includes thermal shutdown, which prevents damage from overheating, and a current limit to protect against overcurrent conditions. Additionally, the regulator offers a low dropout operation, ensuring continuous power delivery even when the input voltage is close to the output voltage.

Key features of the LT1507IS8-3.3 include:

• Fixed 3.3V output voltage
• Wide input voltage range: 4.5V to 60V
• 1.5A output current
• 500kHz switching frequency
• Thermal shutdown and current limit protection
• Low dropout operation
• SO-8 package for compact designs

Designers will appreciate the simplicity of incorporating the LT1507IS8-3.3 into their designs, as its fixed output voltage eliminates the need for external resistors to set the voltage, and its high-frequency operation allows for the use of smaller passive components. Whether it's for new designs or as a drop-in replacement for existing applications, the LT1507IS8-3.3 is a reliable and efficient solution for regulated power supply requirements.
