LM2940HR-5.0 Low Dropout Voltage Regulator - 5V 1A Output
The LM2940HR-5.0 is a high-performance low dropout (LDO) linear voltage regulator manufactured by TAEJIN, designed to deliver a stable 5V fixed output with up to 1A current capability. This precision voltage regulator is ideal for embedded systems, microcontroller power supplies, and battery-powered applications requiring reliable voltage regulation.
Key Features & Benefits
- Low Dropout Voltage: Only 0.4V dropout at 1A load ensures efficient operation even when input voltage is close to output
- Wide Input Range: Accepts input voltages up to 60V, providing flexibility for various power supply designs
- High PSRR: 72dB power supply rejection ratio at 120Hz filters out input noise for clean output
- Built-in Protection: Short circuit and reverse polarity protection safeguard your circuit from damage
- Extended Temperature Range: Operates reliably from -40°C to 125°C (TJ) for industrial applications
- Surface Mount Package: Compact TO-263-3L package saves board space and simplifies assembly
Applications
The LM2940HR-5.0 is perfectly suited for:
- Microcontroller and FPGA power supplies
- Battery-powered portable devices
- Automotive electronics and industrial control systems
- Embedded systems requiring stable 5V rail
- Post-regulation for switching power supplies
