Linear & Switching Voltage Regulators

LP2980AIM5-3.0 Description

The LP2980AIM5-3.0 is a fixed-output, low-dropout (LDO) linear voltage regulator from Texas Instruments, designed to deliver a stable 3V output with a maximum current of 50mA. Housed in a compact SOT23-5 package, this regulator is optimized for space-constrained applications requiring reliable power management. With an input voltage range up to 16V and a low dropout voltage of 0.22V at 50mA, it ensures efficient operation even with minimal headroom. The device features enable control, allowing for power-saving modes, and includes robust protection mechanisms such as over-current, over-temperature, and short-circuit protection.

LP2980AIM5-3.0 Features

• Low Quiescent Current: 95 µA (typical) minimizes power consumption in battery-operated systems.
• High PSRR: 63dB at 1kHz ensures excellent noise rejection, making it ideal for sensitive analog or RF circuits.
• Wide Input Range: Supports up to 16V, accommodating various power sources.
• Compact & Reliable: SOT23-5 package with MSL 1 (Unlimited) moisture sensitivity, suitable for automated assembly.
• Protection Features: Integrated safeguards against over-current, over-temperature, and short-circuit conditions.
• RoHS3 & REACH Compliant: Meets environmental and regulatory standards for global use.

LP2980AIM5-3.0 Applications

• Portable Electronics: Ideal for wearables, IoT sensors, and handheld devices due to low Iq and small footprint.
• Industrial Systems: Suitable for PLC modules, sensor interfaces, and low-power control circuits requiring stable 3V rails.
• Automotive Electronics: Reliable for infotainment systems, dashboards, and auxiliary power supplies (within input limits).
• Medical Devices: Used in patient monitors, portable diagnostic tools where noise immunity and efficiency are critical.

Conclusion of LP2980AIM5-3.0

The LP2980AIM5-3.0 stands out as a high-performance LDO regulator, combining low dropout, ultra-low quiescent current, and robust protection in a miniature package. Its high PSRR and enable control make it versatile for noise-sensitive and power-conscious designs. While classified as Last Time Buy, it remains a dependable choice for legacy or new projects requiring a 3V, 50mA regulated supply with TI's proven reliability. Engineers should evaluate alternative TI LDOs for future-proof designs, but this model excels in cost-sensitive, space-constrained applications.
