TPS7A8400RGRR** is a low-dropout (LDO) voltage regulator manufactured by **Texas Instruments (TI)**.

The TPS7A8400RGRR is a low-dropout (LDO) voltage regulator manufactured by Texas Instruments (TI). Below are its specifications, descriptions, and features:

Specifications:

  • Input Voltage Range: 1.4V to 6.5V
  • Output Voltage Range: 0.8V to 5.5V (adjustable)
  • Output Current: 4A (maximum)
  • Dropout Voltage: 95mV (typical) at 1A
  • Accuracy: ±1% (over line, load, and temperature)
  • Quiescent Current: 1.1mA (typical)
  • PSRR: 60dB at 1kHz
  • Operating Temperature Range: -40°C to +125°C
  • Package: 20-pin VQFN (RGR)

Descriptions:

The TPS7A8400 is a high-performance, low-noise, ultra-low-dropout linear regulator designed for power-sensitive applications. It provides excellent transient response and high PSRR, making it suitable for noise-sensitive systems such as RF, medical, and industrial applications. The device supports adjustable output voltage and includes features like power-good indication and enable control.

Features:

  • Ultra-Low Dropout Voltage: Enables efficient operation with minimal headroom.
  • High PSRR: Reduces noise in sensitive circuits.
  • Adjustable Output Voltage: Configurable via external resistors.
  • Power-Good (PG) Indicator: Monitors output voltage status.
  • Enable Pin (EN): Allows for power sequencing control.
  • Thermal Shutdown & Overcurrent Protection: Ensures safe operation.
  • Small Footprint: 20-pin VQFN package (3.5mm × 4.5mm).

This LDO is ideal for applications requiring stable, low-noise power supplies, such as FPGAs, DSPs, and RF modules.
