Overview
The LD39130SJ33R is a low-dropout linear regulator from STMicroelectronics, delivering a fixed 3.3 V output with a maximum current of 300 mA. It operates within an input voltage range of 1.4 V to 5.5 V and features a typical dropout voltage of 300 mV at full load. The device maintains a quiescent current of 45 uA and offers a power supply rejection ratio of 70 dB. Packaged in a FlipChip-4 (4-UFBGA) surface-mount format, it supports operation across a temperature range of -40°C to +125°C.
Feature Summary
- Provides stable regulated power for sensitive electronic circuits through fixed voltage output regulation.
- Integrates comprehensive protection mechanisms including overcurrent limiting, thermal shutdown, and soft-start functionality.
- Utilizes a compact FlipChip-4 package designed for efficient surface-mount assembly in space-constrained applications.
Applications
- Portable consumer electronics requiring efficient power management
- Battery-powered devices needing low quiescent current consumption
- Embedded systems utilizing microcontrollers or sensors
Procurement Notes
Verify the specific suffix 'J33' confirms the 3.3 V fixed output variant when sourcing. Confirm the FlipChip-4 package type matches your PCB footprint requirements. Ensure compatibility with RoHS3 standards if required by your manufacturing process. Cross-reference datasheet specifications against your system's thermal and electrical constraints before finalizing procurement.
Selection Notes
Select this component when a fixed 3.3 V rail is required with moderate current demands up to 300 mA. Consider its low quiescent current for battery-operated designs where efficiency is critical. Evaluate the small FlipChip-4 footprint against available board space. Verify that the input voltage range accommodates your source supply variations under all operating conditions.
