The Texas Instruments TPS7A4501DCQRG4 is an ultra-low-dropout (LDO) linear voltage regulator designed for high-performance applications. It can deliver up to 1.5 A of output current with a maximum input voltage of 20 V and a minimum input voltage of 2.1 V. The regulator features a low noise level of 35 µVrms and a high power supply ripple rejection (PSRR) of 68 dB at 1 kHz.
This device provides a stable output voltage with high accuracy, typically 1% at 25°C. The dropout voltage is a low 300 mV at typical conditions, making it suitable for applications where maintaining a small voltage difference between input and output is critical. It supports both fixed output voltages (1.5 V, 1.8 V, 2.5 V, 3.3 V) and an adjustable output range from 1.21 V to 20 V (TPS7A4501 only).
Key features include reverse current protection and an enable function. The TPS7A4501DCQRG4 is designed to be stable with a minimum load capacitance of 10 µF ceramic. It operates within a temperature range of -40°C to 125°C and is available in SOT-223 and TO-263 packages, suitable for surface mount applications.
The input voltage range is 2.1V to 20V.
The output can be adjusted from 1.21V to 20V, or fixed at 1.5V, 1.8V, 2.5V, or 3.3V.
The maximum output current is 1.5A.
The typical dropout voltage is 300 mV.
The typical output noise is 35 µVrms over 10 Hz to 100 kHz.
The operating temperature range is -40°C to 125°C.
The regulator is available in SOT-223 and TO-263 packages.
