TL1963A-33DCQRG4 Description

Short technical summary and product information.

The Texas Instruments TL1963A-33DCQRG4 is a high-performance, 1.5-Ampere low-dropout (LDO) voltage regulator designed for various power management applications. It operates with an input voltage range of 2.4V to 20V and provides a regulated output voltage with a maximum current capability of 1.5A.

Key electrical specifications include a typical dropout voltage of 340mV at 1.5A, low noise of 23µVRMS (10Hz to 100kHz), and a PSRR of 45dB at 100KHz. The regulator features enable functionality, reverse current protection, and reverse voltage protection. It requires a minimum load capacitance of 10µF with an ESR of less than 3Ω for stable operation.

Available in SOT-223 and TO-263 packages, the TL1963A-33DCQRG4 is suitable for surface mount applications. The operating temperature range is -40°C to 125°C, making it robust for demanding environments. Integrated fault protection includes thermal shutdown and overcurrent protection.

This LDO regulator is well-suited for applications requiring clean power delivery, such as battery-powered devices, portable electronics, and noise-sensitive analog circuits.
