REG102NA-A/250 Description

Short technical summary and product information.

The Texas Instruments REG102NA-A/250 is a linear, low-dropout (LDO) voltage regulator designed for adjustable output voltage applications. It offers a maximum output current of 250mA and operates within a temperature range of -40°C to 85°C.

 

Key electrical characteristics include a low dropout voltage of 150mV typical at 250mA, a PSRR of 65dB at 120Hz, and low noise of 28 µVrms. The regulator also features over current and over temperature protection.

 

This device is available in a compact SOT-23-5 surface-mount package, making it suitable for space-constrained designs. It includes an enable control feature and operates with a quiescent current of 600 µA at full load, reducing power consumption.

 

Applications for the REG102NA-A/250 include portable communication devices and battery-powered equipment where efficient voltage regulation is critical.
