LT1506CS8-3.3#PBF

Overview

The LT1506CS8-3.3#PBF is a fixed-output switching regulator from Analog Devices, delivering a stable 3.3V output. It operates within an input voltage range of 2.7V to 40V and provides up to 1A of continuous load current. The device integrates a 1.2MHz switching frequency, enabling the use of compact external components. Packaged in an 8-pin SOIC, it features thermal shutdown and current limit protection for robust operation in space-constrained power supply designs.

Feature Summary

Integrates high-side and low-side switches with a fixed 1.2MHz oscillator
Provides precise 3.3V fixed output voltage regulation
Includes built-in thermal shutdown and cycle-by-cycle current limiting

Applications

Battery-powered portable equipment
Point-of-load regulation modules
DC-to-DC conversion in industrial control systems

Procurement Notes

Verify the complete part number including the suffix #PBF to confirm lead-free compliance and RoHS status. Ensure the ordering code matches the specific package variant (SO-8) and temperature grade (Commercial). Cross-reference the manufacturer's official documentation to confirm pinout compatibility and recommended operating conditions before integration into the design.

Selection Notes

Select this component when a fixed 3.3V output is required from a wide input voltage range up to 40V. It is suitable for applications needing moderate current capability without the complexity of adjustable feedback networks. Consider the integrated switch ratings and thermal performance relative to the expected ambient temperature and PCB copper area available for heat dissipation.

Part Context

This part belongs to the LT1506 family of monolithic switching regulators designed for high-efficiency step-down conversion. Unlike adjustable variants, this specific model is optimized for standard logic supply voltages. It simplifies design by eliminating external feedback resistors while maintaining high efficiency through synchronous rectification at the specified switching frequency.
