TPS7A8400ARGRT Description

Short technical summary and product information.

The Texas Instruments TPS7A8400ARGRT is an active 3-A, low-VIN, low-noise, high-accuracy, ultra-low-dropout voltage regulator. It operates with an input voltage range of 1.1 V to 6.5 V with BIAS and 1.4 V to 6.5 V without BIAS. The output voltage is adjustable from 0.8 V to 5.15 V, with ANY-OUT™ operation from 0.8 V to 3.95 V.

 

Key electrical specifications include a maximum output current of 3 A, a typical dropout voltage of 110 mV at 3 A, and a maximum dropout voltage of 180 mV at 3 A with BIAS. The device boasts a high accuracy of 0.75% over line, load, and temperature. Output voltage noise is a low 4.4 µVrms, and Power Supply Ripple Rejection (PSRR) is 25 dB at 100 KHz and 40 dB at 500 kHz. Quiescent current is typically 2.8 mA.

 

This regulator features control functions such as Enable, Power Good, and Soft Start, along with protection features including Over Current, Over Temperature, and Under Voltage Lockout (UVLO). It requires a minimum load capacitance of 47 µF.

 

The TPS7A8400ARGRT is supplied in a 20-VQFN (3.5x3.5 mm) package, designed for surface mounting. The operating temperature range is -40°C to 125°C (TJ).
