TQL821CSV50 RLG Image

The TQL821CSV50 RLG from Taiwan Semiconductor is an Automotive Qualified Linear LDO Regulator that is ideal for automotive or other supply systems. It requires an input voltage of 3 - 50 V. This regulator provides a fixed output voltage of 5 V and a drop-out voltage of 0.07 V. It is designed to offer a high output voltage accuracy of ±2% in both load and line regulation. This AEC-Q100 qualified LDO connects a high voltage tolerant Enable pin to a microcontroller or digital control system that switches ON the device when the input voltage is high and disables when the input signal is low.

The TQL821CSV50 RLG embeds a single small ceramic capacitor at the output to exhibit fast regulation and provide good stability. It integrates the current limit circuit, over-temperature protection (OTP), and thermal shutdown to prevent overload-related damages. This RoHS-compliant regulator is available in a surface-mount package that measures 4.9 x 6.00 x 1.7 mm.
