Product Description
STMicroelectronics LD39130SPUR is a highly efficient voltage regulator designed for surface-mount applications with a compact DFN 6-pin package measuring 1.4 mm length, 1.3 mm width, and 350 μm height. It operates with an input voltage range from 1.5 V up to 5.5 V, making it suitable for various low-voltage electronics and power management systems.
Featuring ultra-low dropout voltage (typically 300 mV at 300 mA load) and very low quiescent current consumption (1 μA in green mode, 45 μA in normal mode, and 0.1 μA in off mode), this device is ideal for portable and battery-powered applications requiring efficient power regulation.
The regulator provides a guaranteed output current of 300 mA with an output voltage tolerance of ±1.0% at 25 °C, ensuring high precision and stability. It includes automatic green mode functionality and logic-controlled electronic shutdown to enhance power saving during idle periods.
Internal features such as soft-start, current foldback, and thermal protections enhance device reliability under various operating conditions. The device is compatible with ceramic capacitors with a minimum output capacitance of 330 nF.
Operating temperature ranges from -40 °C to 125 °C, making it suitable for demanding industrial, automotive, and consumer electronics environments. The regulator is manufactured in China and meets high-quality standards with no automotive-specific standard certification.
Input voltage range from 1.5 V to 5.5 V for versatile applications. Ultra low dropout voltage enhances efficiency. Very low quiescent current minimizes power consumption. Automatic green mode and shutdown reduce energy use during standby.
Thermal and current foldback protections improve safety. Compact and low-profile DFN 6-pin package integrates easily into space-constrained designs. Wide operating temperature range supports industrial and automotive applications.
Ideal for industrial, automotive, and consumer electronics power management. Explore more Voltage Regulators and power management ICs in our Electronics & Electricals category at EnvMart.
