The TPS74901RGWT from Texas Instruments is a high-performance, adjustable ultra-low-dropout (LDO) linear voltage regulator designed for demanding applications. It can supply a continuous output current of up to 3A, making it suitable for power-hungry systems.
This regulator features a wide input voltage range from 0.8V to 5.5V and an adjustable output voltage range of 0.8V to 3.6V. Key electrical characteristics include a low dropout voltage of 120mV typical at 3A, low noise (20 µVrms), and good PSRR performance up to 28dB at 100 KHz. It also includes essential control features such as Enable, Power Good, and a programmable Soft Start for controlled power-up sequences.
Protection features are robust, encompassing Over Current, Over Temperature, Short Circuit, and Under Voltage Lockout (UVLO) to ensure system reliability. The device is designed for stability with any output capacitor greater than or equal to 2.2µF.
The TPS74901RGWT is supplied in a compact 20-VQFN Exposed Pad package, measuring 5mm x 5mm, suitable for surface mount applications where space is a constraint. Its operating temperature range is -40°C to 125°C.
