Overview
The L5972D013TR is a monolithic step-down switching regulator IC from STMicroelectronics, operating within an input voltage range of 4.4V to 36V. It delivers a continuous output current of 2A with an adjustable output voltage spanning from 1.235V to 35V. The device integrates a fixed 250kHz switching frequency and features a low quiescent current of 2.5mA. Designed for surface-mount applications, it utilizes an 8-SOIC package (3.90mm width) and supports a junction temperature range of -40°C to +150°C.
Feature Summary
- Integrates a high-efficiency buck topology with a fixed 250kHz internal oscillator
- Provides robust thermal protection and current limiting for reliable operation
- Features low standby current consumption to extend battery life in portable systems
Applications
- Battery-powered portable equipment requiring efficient voltage regulation
- Industrial control systems operating under wide temperature conditions
- General-purpose DC-DC conversion in embedded electronics
Procurement Notes
Verify the exact part number suffix against official STMicroelectronics documentation to confirm packaging and tape specifications. Ensure compatibility with the required SOIC-8 footprint and verify that the 2A output capability meets the specific load requirements of the target application design.
Selection Notes
Select this component when a single-output adjustable buck converter with 2A capacity is required. It is suitable for designs needing a wide input voltage range up to 36V. Consider the 8-SOIC package constraints and the fixed 250kHz switching frequency when designing external passive components.
Part Context
This component belongs to the L5972D series of switching regulators. It shares architectural similarities with the L5970D but offers higher output current capability. The device is part of STMicroelectronics' portfolio of power management integrated circuits designed for cost-effective and space-constrained applications.
Replacement Considerations
The L5972D is the base part number for this device family. Verify if alternative suffixes are available for different packaging options such as tube or cut tape formats directly from manufacturer datasheets.
