TPS7A9001DSKR Description

Short technical summary and product information.

The Texas Instruments TPS7A9001DSKR is an adjustable ultra-low-dropout (LDO) linear voltage regulator designed for high-performance applications. It provides a stable output voltage with low noise and high power-supply rejection ratio (PSRR).

 

Key electrical specifications include a wide input voltage range from 1.4 V to 6.5 V and an adjustable output voltage range from 0.8 V to 5.7 V. The regulator can supply up to 500 mA of output current. It features low output noise of 4.7 µV RMS (10 Hz–100 kHz) and a typical dropout voltage of 75 mV at 0.5 A. The PSRR is 50 dB at 100 kHz.

 

Control features include Enable, Power Good, and Soft Start, allowing for controlled power-up sequences. Protection features include Over Temperature and Under Voltage Lockout (UVLO).

 

The TPS7A9001DSKR is available in a 10-pin WSON package with dimensions of 2.5 mm × 2.5 mm. This surface-mount package is suitable for space-constrained designs. The operating temperature range is -40°C to 125°C (TJ).
