Frequently Asked Questions
What is the dropout voltage of the TL1963A-33DCQR?
The TL1963A-33DCQR has a typical dropout voltage of 0.34V and a maximum of 0.55V at full 1.5A load. This low dropout allows the device to regulate 3.3V output from input voltages as low as 3.8V, making it highly efficient in battery-powered applications.
What is the maximum input voltage for the TL1963A-33DCQR?
The TL1963A-33DCQR supports an input voltage range of 3.8V to 20V, with an absolute maximum rating of 20V. This wide input range makes it suitable for use in systems powered by 5V, 9V, 12V, or unregulated DC supplies while delivering a clean 3.3V regulated output.
What package does the TL1963A-33DCQR come in?
The TL1963A-33DCQR is housed in a SOT-223 5-pin (R-PDSO-G6) surface-mount package. The SOT-223 package provides good thermal dissipation through its exposed tab, allowing the regulator to deliver its full 1.5A output current without requiring a large heatsink in many applications.
What are typical applications for the TL1963A-33DCQR?
The TL1963A-33DCQR is ideal for noise-sensitive applications such as RF front-ends, analog-to-digital converters, precision sensors, and audio circuits. Its fast transient response also makes it well-suited for powering microcontrollers, FPGAs, and DSPs that experience rapid load current changes.
