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.
