TITLV75533PDBVR
Overview
The TLV75533PDBVR is a low-dropout (LDO) linear voltage regulator from Texas Instruments that provides a fixed 3.3V output from an input range of 1.45V to 5.5V. It is capable of delivering up to 500mA of output current while maintaining a low quiescent current of 25 microamps. This device features a fast transient response and high PSRR of 52dB from 1kHz to 1MHz, making it suitable for noise-sensitive power rails.
Why Choose This Part
The regulator includes internal foldback current limiting and thermal protection to prevent device failure during fault conditions. Its low dropout voltage allows for efficient operation even as the input voltage approaches the 3.3V set point, while the small SOT-23-5 package minimizes PCB footprint.
Applications
Key Specifications
Getting Started
To use this device, place a 1 microfarad ceramic capacitor at both the input and output pins for stability. Ensure the Enable (EN) pin is pulled high to activate the regulator, or connect it to a GPIO for power sequencing. Thermal performance should be verified by calculating the power dissipation based on the voltage drop and 500mA maximum load.
