Linear & Switching Voltage Regulators

LM2941LD Description

The LM2941LD from Texas Instruments is a 1A low-dropout (LDO) adjustable linear voltage regulator designed for applications requiring stable power with minimal voltage overhead. It supports an input voltage range up to 26V and delivers an adjustable output from 5V to 20V, making it versatile for various power supply designs. Packaged in an 8-pin WSON (8WSON) surface-mount form factor, it is optimized for space-constrained PCB layouts. With a low dropout voltage of 1V at 1A, it ensures efficient regulation even when the input voltage is close to the output requirement.

LM2941LD Features

• Adjustable Output (5V–20V): Provides flexibility for diverse voltage requirements.
• High Current Capability (1A): Suitable for powering moderate-load circuits.
• Low Dropout Voltage (1V @ 1A): Enhances efficiency in low headroom conditions.
• Enable Control: Allows power management via an external logic signal.
• Robust Protection: Includes over-temperature, reverse polarity, and short-circuit protection for reliability.
• Low Quiescent Current (10 mA): Minimizes power loss in standby mode.
• RoHS3 & REACH Compliant: Meets environmental and regulatory standards.
• Wide Operating Temperature Range: Ensures stable performance in harsh conditions.

LM2941LD Applications

• Automotive Electronics: Ideal for infotainment systems, sensors, and ECUs due to its reverse polarity protection and wide input range.
• Industrial Control Systems: Provides stable power for PLCs, motor drivers, and instrumentation.
• Portable Devices: Efficiently powers battery-operated equipment with low dropout.
• Embedded Systems: Suitable for microcontrollers, FPGAs, and peripherals requiring adjustable voltage rails.
• Telecom Infrastructure: Ensures reliable voltage regulation in base stations and networking hardware.

Conclusion of LM2941LD

The LM2941LD stands out as a high-performance, adjustable LDO regulator with robust protection features and low dropout characteristics. Its 1A output capability, wide input range, and compact packaging make it an excellent choice for automotive, industrial, and embedded applications. While it is in Last Time Buy status, its reliability and efficiency ensure it remains a viable solution for legacy and new designs requiring stable power management.
