REG101NA-2.5/250 Description

Short technical summary and product information.

The REG101NA-2.5/250 from Texas Instruments is a linear, low-dropout (LDO) voltage regulator designed for applications requiring stable power.

 

This device features a fixed 2.5V output voltage and can supply up to 100mA of current. It operates with an input voltage range from 1.8V to 10V. Key electrical characteristics include a typical dropout voltage of 60mV at 100mA, low noise of 23 µVrms, and a PSRR of 46dB at 100 KHz. The regulator includes enable functionality and foldback overcurrent protection for enhanced system safety.

 

Packaged in a surface-mount SOT-23-5 configuration, the REG101NA-2.5/250 is suitable for space-constrained designs. Its operating temperature range is -40°C to 85°C, making it versatile for various environmental conditions.

 

Applications for this LDO include portable communication devices, battery-powered equipment, personal digital assistants, modems, bar-code scanners, and backup power supplies where efficient and stable voltage regulation is critical.
