TQL851CSV33 RLG Image

The TQL851CSV33 RLG is a Low Dropout Linear Voltage Regulator that is ideal for automotive and other power supply systems. This LDO requires an input voltage of 3 - 50 V. It provides a fixed output voltage of 3.3 V and has a dropout voltage of 0.06 V. This regulator is designed to offer a high accuracy output voltage of ±2% in both load and line regulation. It has an enable pin to switch the system between ON and OFF states to maintain power dissipation. 

This AEC-Q100 qualified LDO embeds a single small ceramic capacitor to provide both fast regulations as well as good stability, thereby ensuring optimum performance. It integrates thermal shutdown and current-limiting functions to prevent over-load-related damages. This RoHS-compliant regulator is available in a surface-mount package that measures 4.9 x 6.0 x 1.7 mm.
