Product Description
STMicroelectronics L4931ABDT33-TR is a low dropout (LDO) linear voltage regulator designed to maintain a steady voltage output with a maximum input voltage rating of 20V. Its surface mount package with three pins enables easy integration into printed circuit boards for compact electronic assemblies.
The device achieves high efficiency by operating with a low input-output differential voltage while consuming only 600μA quiescent current, ideal for battery-powered and low power applications. Its positive polarity design makes it suitable for a variety of power management scenarios in consumer, industrial, and automotive electronics.
With compact dimensions of 6.6mm length, 6.2mm width, and 2.4mm height, the L4931ABDT33-TR fits well in space-constrained environments. It operates reliably up to 125°C, making it suitable for harsh operating conditions and complies with AEC-Q100 automotive standards.
The regulator provides low noise output and high power supply rejection ratio (PSRR), essential for minimizing interference in delicate analog and digital circuits. Typical applications include voltage regulation in embedded systems, automotive electronics modules, industrial instrumentation, and power supply circuits.
Stable output voltage regulation at low dropout voltages. Low quiescent current to conserve energy. Small 3-pin surface mount package for space efficiency. Wide operating temperature range for reliability. Automotive-grade qualification for high-reliability systems.
Excellent noise and ripple rejection characteristics.
This voltage regulator is part of STMicroelectronics' broad portfolio of power management ICs available on EnvMart, offering reliable performance for multiple industrial and electronic applications.
