Advanced Power Management with STMicroelectronics LD39050PUR
The STMicroelectronics LD39050PUR represents a new generation of adjustable linear voltage regulators designed to meet the demanding requirements of modern electronic systems. This high-performance IC combines precision regulation with comprehensive protection features in a compact 6-DFN package, making it ideal for space-constrained applications requiring reliable power management solutions.
Technical Excellence in Voltage Regulation
With its adjustable output voltage range from 0.8V to 5.1V, the LD39050PUR offers unparalleled flexibility for diverse electronic designs. The device maintains stable output even under varying load conditions, thanks to its advanced compensation circuitry and 500mA output current capability. Its low dropout voltage of 0.4V at full load ensures efficient operation in battery-powered systems where every millivolt counts.
| Parameter | Specification |
|---|---|
| Input Voltage | Up to 5.5V |
| Output Current | 500mA |
| Quiescent Current | 50µA |
| PSRR | 65dB @ 1kHz |
Enhanced System Reliability
Engineers will appreciate the LD39050PUR's built-in protection features that safeguard both the regulator and connected components. The integrated thermal shutdown prevents damage from excessive junction temperatures, while the over-current and short-circuit protection mechanisms ensure safe operation under fault conditions. These safety features make it particularly suitable for automotive and industrial applications where reliability is paramount.
The device's enable and power good control features provide additional system management capabilities. Designers can use these signals for power sequencing in complex systems or to implement low-power modes that extend battery life in portable devices. The 65dB power supply rejection ratio (PSRR) ensures clean output voltage even when powering noise-sensitive analog circuits.
Optimized for Modern Electronics
With its 6-VDFN exposed pad package, the LD39050PUR combines thermal efficiency with space-saving design. The surface-mount package facilitates automated assembly while maintaining excellent thermal performance through its exposed pad. This makes it particularly well-suited for applications in wearable technology, IoT devices, and portable medical equipment where size and thermal management are critical design factors.
The regulator's ultra-low quiescent current of 50µA and maximum supply current of 200µA make it an excellent choice for battery-powered applications. Its performance across the -40°C to 125°C temperature range ensures reliable operation in harsh environments, from automotive under-hood systems to industrial automation equipment. The adjustable output feature eliminates the need for multiple fixed-voltage regulators in inventory, simplifying design and procurement processes.
