The TQL821CSV33 is a Low Dropout Linear Voltage Regulator that is ideal for automotive power supply systems and general power supply applications. It requires an input voltage of 3 V to 50 V. This LDO provides a fixed output voltage of 3.3 V and has a dropout voltage of less than 170 mV. It is designed to offer a high accuracy output voltage tolerance of ±2% in both load and line regulation. This AEC-Q100 qualified LDO connects an enable pin that switches the system between ON and OFF states to maintain power dissipation. It uses a single small ceramic capacitor to provide fast regulation and good stability, thereby ensuring optimum performance. This RoHS-compliant LDO regulator integrates the current limit function and comparator-enabled thermal shutdown circuitry to shut down the system to prevent over-temperature and over-load-related damages. It is available in a surface-mount package that measures 4.9 x 6 x 1.7 mm.
