Texas Instruments LM111733QKVURQ1 Automotive Low-Dropout Voltage Regulator
The LM111733QKVURQ1 is a high-performance automotive-grade low-dropout (LDO) voltage regulator from Texas Instruments, designed to deliver reliable 3.3V fixed output at 1A current capacity. Engineered for demanding automotive applications, this regulator meets stringent AEC-Q100 qualification standards and operates flawlessly across extreme temperature ranges from -40°C to 125°C.
Key Features & Benefits
- Automotive-Grade Reliability: AEC-Q100 qualified for automotive electronics applications
- Fixed 3.3V Output: Stable voltage regulation with 1A output current capability
- Wide Input Voltage Range: Accepts input voltages up to 18V
- Low Quiescent Current: Only 110 µA for improved power efficiency
- Excellent PSRR: 60dB to 40dB power supply rejection ratio (1kHz to 1MHz)
- Comprehensive Protection: Over-current, over-temperature, and under-voltage lockout (UVLO) protection
- Compact Surface Mount Package: TO-252-3 DPAK package for space-efficient PCB designs
- Extended Temperature Range: Operates reliably from -40°C to 125°C (TA)
Applications
The LM111733QKVURQ1 is ideal for automotive electronic control units (ECUs), infotainment systems, advanced driver-assistance systems (ADAS), body control modules, and other safety-critical automotive applications requiring stable 3.3V power rails. Its robust protection features and automotive qualification make it suitable for harsh automotive environments.
Performance Advantages
This automotive LDO voltage regulator delivers exceptional performance in demanding conditions. The low quiescent current of 110 µA minimizes power consumption during standby modes, making it perfect for battery-powered automotive systems. The excellent power supply rejection ratio (PSRR) of 60dB to 40dB across the 1kHz to 1MHz frequency range ensures clean, stable output voltage even with noisy input power sources common in automotive electrical systems.
Protection & Reliability
Safety is paramount in automotive applications. The LM111733QKVURQ1 incorporates multiple protection mechanisms including over-current protection to prevent damage from excessive load conditions, over-temperature protection to safeguard against thermal stress, and under-voltage lockout (UVLO) to ensure proper operation only when input voltage is within acceptable limits. These features combine to deliver the reliability required for automotive-grade components.
