LP3980-18B5F Description

Short technical summary and product information.

The LP3980-18B5F from LOWPOWER is a linear Low Dropout (LDO) voltage regulator designed for efficient power management. This component provides a stable, fixed output voltage of 1.8V and can deliver up to 500mA of current.

 

Key electrical characteristics include a typical dropout voltage of 500mV at 500mA, a low quiescent current of 20uA, and a high Power Supply Rejection Ratio (PSRR) of -80dB at 217Hz. The device operates within a temperature range of -40°C to +85°C and has a maximum input voltage of 5.5V.

 

Integrated protection features such as thermal shutdown and overcurrent protection enhance the reliability and safety of the circuit. The LP3980-18B5F is supplied in a compact SOT23-5 package, making it suitable for space-constrained applications. Its positive output polarity and low noise output of 100uVrms are beneficial for sensitive electronic designs.

 

This LDO regulator is well-suited for various battery-powered and portable electronic devices where power efficiency and stable voltage regulation are critical. The SOT23-5 package facilitates surface-mount assembly.
