TPS7A4700RGWT Description

Short technical summary and product information.

The Texas Instruments TPS7A4700RGWT is a high-performance, positive voltage, ultralow-noise, low-dropout (LDO) linear regulator designed for demanding applications. It can source a 1-A load and operates with an input voltage range from 3 V to 36 V.

 

Key electrical specifications include an output voltage noise of 4 µVRMS (at 10 Hz, 100 kHz) and a Power-Supply Ripple Rejection (PSRR) of 82 dB at 100 Hz. The device offers an adjustable output voltage range from 1.4 V to 20.5 V and features a maximum dropout voltage of 0.45V at 1A. Protection features include over current, over temperature, and under voltage lockout (UVLO).

 

Designed with bipolar technology, the TPS7A4700RGWT is ideal for high-accuracy instrumentation applications where clean voltage rails are critical. This includes powering operational amplifiers, analog-to-digital converters (ADCs), and digital-to-analog converters (DACs). It is also suitable for post DC-DC converter regulation, filtering out inherent switching ripple.

 

The regulator is available in a 20-VQFN (5x5 mm) package with surface mount mounting type. It operates within a temperature range of -40°C to 125°C and includes a CMOS logic-level compatible enable pin for control.
