LD39115J10R

Overview

The LD39115J10R is a fixed-output low-dropout linear voltage regulator manufactured by STMicroelectronics. It provides a fixed output voltage of 1.0 V with a maximum load current capability of 150 mA. The device operates within an input voltage range of 1.5 V to 5.5 V and features a typical dropout voltage of 80 mV at a 100 mA load. Quiescent current is specified at 50 µA, with a maximum supply current of 70 µA. Power supply rejection ratio ranges from 74 dB to 67 dB between 1 kHz and 10 kHz. The component is housed in a compact 4-flipchip package measuring 0.79 x 0.79 mm.

Feature Summary

Ultra-low dropout voltage design for efficient power management
Very low quiescent current consumption for battery-powered applications
Logic-controlled enable function for electronic shutdown
Integrated short-circuit constant current limiting and thermal protection

Applications

Low-power battery-operated portable devices
Healthcare and wellness equipment
Embedded systems requiring stable low-voltage rails

Procurement Notes

Verify the specific suffix 'J10R' against official STMicroelectronics documentation to confirm the 1.0 V fixed output configuration. Ensure compatibility with the 4-flipchip (FCBGA) footprint during PCB layout. Confirm RoHS3 compliance status through the manufacturer's latest datasheet before finalizing procurement specifications.

Selection Notes

Select this component when a precise 1.0 V rail is required with minimal voltage drop under load. The ultra-compact flip-chip package suits space-constrained designs. Verify that the application environment remains within the -40°C to 125°C operating temperature range and that ceramic capacitors are used for stability as per datasheet requirements.

Part Context

This part belongs to the LD39115 family of low-noise, low-quiescent current LDO regulators. The series offers various fixed output voltages ranging from 0.8 V to 4.5 V. The 'J' suffix typically denotes the flip-chip packaging variant, while the numeric suffix indicates the specific output voltage setting.
