Linear & Switching Voltage Regulators

LP2980IM5X-ADJ Description

The LP2980IM5X-ADJ from Texas Instruments is a low-dropout (LDO) linear voltage regulator designed for ultra-low-power applications. With an adjustable output voltage range of 1.23V to 15V, it delivers a 50mA output current while maintaining high efficiency. The device operates with a maximum input voltage of 16V and features a quiescent current of just 95 µA, making it ideal for battery-powered and energy-sensitive systems. Its 63dB PSRR (1kHz) ensures excellent noise rejection, critical for precision analog and RF circuits.

LP2980IM5X-ADJ Features

• Ultra-Low Quiescent Current (95 µA): Minimizes power loss in standby modes.
• High PSRR (63dB at 1kHz): Reduces noise for sensitive applications.
• Adjustable Output (1.23V–15V): Flexible for diverse voltage requirements.
• Low Dropout Voltage (0.22V @ 50mA): Enhances efficiency in low-voltage conditions.
• Robust Protection: Includes over-current, over-temperature, and short-circuit protection for reliability.
• Enable Control: Allows power management via an external signal.
• Surface-Mount Package (SOT-23-5): Compact footprint for space-constrained designs.
