Overview
The LDL40PURY is a high-accuracy, adjustable low-dropout linear voltage regulator manufactured by STMicroelectronics. It supports an input voltage range from 3.3 V to 40 V and delivers a guaranteed output current of 200 mA. The device features an adjustable output voltage range between 1.2 V and 12 V with a typical dropout voltage of 700 mV at full load. It operates within a junction temperature range of -40 °C to +150 °C and includes logic-controlled electronic shutdown for ultra-low quiescent current consumption below 0.3 µA.
Feature Summary
- High accuracy voltage regulation suitable for direct connection to automotive batteries or industrial power sources
- Extended input voltage capability up to 40 V to withstand load dump transients common in automotive systems
- Ultra-low quiescent current design that extends battery life in always-on standby applications
- Integrated protection mechanisms including thermal shutdown, internal current limit, and active output discharge
Applications
- Automotive electronics requiring AEC-Q100 Grade 1 qualification
- Industrial battery-powered equipment needing stable voltage regulation
- Always-on standby systems prioritizing minimal power consumption
- Portable devices utilizing generic battery inputs
Procurement Notes
Verify the specific suffix 'URY' against the official STMicroelectronics datasheet to confirm package type and tape-and-reel specifications. Ensure compatibility with DFN6 (2x2) wettable flanks for automated optical inspection. Confirm that the adjustable output configuration matches the required external resistor network values for the target voltage setting.
Selection Notes
Select this component when designing circuits that require robust performance under wide input voltage variations and harsh thermal environments. The adjustable output feature provides flexibility for various voltage rails without changing the IC. Consider the small footprint for space-constrained PCB layouts while ensuring adequate thermal management for the DFN6 package during continuous operation.
Part Context
The LDL40 series represents STMicroelectronics' solution for precision power management in demanding environments. This specific part belongs to the family of ultralow dropout regulators designed for high reliability. It complements other fixed-voltage variants within the same series, offering designers the ability to customize output levels while maintaining consistent electrical characteristics and protection features across the product line.
Replacement Considerations
Direct substitutes include other LDL40 series variants such as LDL40PUxxRY for fixed voltages. Verify pinout compatibility and thermal resistance requirements before swapping. Ensure any replacement maintains the AEC-Q100 Grade 1 certification if used in automotive contexts.
