Linear & Switching Voltage Regulators

TPS74301RGWT Description

The TPS74301RGWT from Texas Instruments is a high-performance, adjustable positive linear voltage regulator designed to deliver 1.5A output current with an input voltage range up to 5.5V. This single-channel regulator offers an adjustable output voltage from 0.8V to 3.6V, making it highly versatile for low-voltage applications. The device features a low dropout voltage (0.12V at 1.5A), ensuring efficient operation even with minimal headroom. With 115 µA quiescent current and 1.5 mA supply current, it is optimized for power-sensitive designs. Packaged in a 20-VQFN (RGWT), it is suitable for surface-mount applications requiring compact footprints.

TPS74301RGWT Features

• High Efficiency: Low dropout voltage (0.12V @ 1.5A) minimizes power dissipation.
• Advanced Control & Protection: Includes enable, power good, and tracking functions, along with over-current, over-temperature, short-circuit, and UVLO protection.
• Excellent Noise Performance: PSRR of 73dB (1kHz) to 42dB (800kHz) ensures stable output in noisy environments.
• Low Quiescent Current: 115 µA Iq enhances battery life in portable applications.
• Robust Packaging: 20-VQFN (RGWT) with MSL 2 (1 Year) rating ensures reliability in industrial environments.
• Compliance: ROHS3 and REACH unaffected, meeting global environmental standards.

TPS74301RGWT Applications

• Portable Electronics: Ideal for battery-powered devices due to low Iq and high efficiency.
