L6935TR ST Linear Voltage Regulator | 20-VFQFPN (4x4) | 3A Output, 0.5V Dropout

Product Overview

The L6935TR from STMicroelectronics is a high-performance, low-dropout (LDO) linear voltage regulator designed for applications requiring high current and low noise. Housed in a compact 20-VFQFPN (4x4 mm) package, it delivers up to 3A output current with a dropout voltage as low as 0.5V at full load. The device features an adjustable output voltage from 0.8V to 5.5V, making it suitable for powering core voltages of FPGAs, DSPs, and microcontrollers. Its excellent line and load transient response, combined with low output noise, make it ideal for noise-sensitive applications such as RF circuits and precision analog systems.
