The LP3982IMM-ADJ/NOPB is a low-dropout (LDO) linear voltage regulator manufactured by Texas Instruments. This chip device operates with an input voltage range of 2.7V to 17V and provides a highly adjustable output voltage from 0.8V to 6V, making it suitable for a wide variety of applications requiring precise voltage regulation. The IC features a maximum output current of 500mA, delivers ultra-low noise performance (typically 22μV RMS), and operates efficiently across a broad temperature range (-40°C to 125°C). Available in a compact SOT-23-5 package with an exposed pad (NOPB variant) for enhanced thermal management, this LDO is ideal for space-constrained designs.
Linear Voltage Regulator IC LP3982IMM-ADJ/NOPB Key Features and Applications
The LP3982IMM-ADJ/NOPB is designed for high-performance applications where low noise, stability, and efficiency are critical. Key features include:
- Adjustable Output Voltage: Enables customization for diverse system requirements.
- Low Dropout Voltage: Maintains stable output even with minimal headroom (as low as 35mV at full load).
- High PSRR: Suppresses input ripple and noise, ensuring clean power delivery for sensitive circuits (up to 80dB at 1kHz).
- Fast Transient Response: Minimizes voltage droop during load changes, crucial for digital and analog systems.
This LDO is widely used in portable electronics (e.g., smartphones, tablets), communication systems (base stations, IoT devices), industrial automation, and medical equipment where noise-sensitive components such as ADCs, DACs, and RF circuits are integrated. Its low power consumption and thermal efficiency also make it suitable for battery-powered applications.
