STMicroelectronics L4931ABDT50-TR Linear Voltage Regulator: Precision Power Management in Compact Design
Engineered for reliability and efficiency, the STMicroelectronics L4931ABDT50-TR Linear Voltage Regulator delivers stable 5V output at 250mA current in a compact DPAK package. This fixed-output positive linear regulator combines advanced protection features with low dropout voltage (0.8V max at 250mA), making it ideal for applications requiring consistent voltage regulation under varying load conditions.
Key Technical Specifications
| Input Voltage | Up to 20V |
| Output Voltage | 5V (Fixed) |
| Output Current | 250mA |
| Dropout Voltage | 0.8V @ 250mA |
| Operating Temperature | -40°C to 125°C |
Designed for modern electronics, this regulator features built-in over-temperature and over-current protection while maintaining minimal quiescent current (1mA typical). Its surface-mount TO-252-3 package with thermal tab enables efficient heat dissipation in space-constrained designs.
With a wide -40°C to 125°C operating temperature range and 70dB PSRR (120Hz-10kHz), the L4931ABDT50-TR excels in industrial control systems, consumer electronics, and automotive applications where voltage stability is critical. The device's low 0.8V dropout voltage ensures optimal performance even with fluctuating input sources.
Performance Comparison
| Parameter | L4931ABDT50-TR | Typical Competitor A |
| Dropout Voltage | 0.8V | 1.2V |
| Quiescent Current | 1mA | 5mA |
| PSRR | 70dB | 55dB |
As part of STMicroelectronics' L49xx series, this regulator offers superior thermal management through its DPAK package with exposed thermal pad. The device meets RoHS compliance standards while providing tape & reel packaging for automated PCB assembly processes.
