The 5 V low-drop fixed linear regulator regulates input voltages from 5.5 V to 45 V to a nominal 5.0 V output. It supports more than 120 mA output current with ±2% output-voltage tolerance over specified load and line conditions. The device includes short-circuit protection, overtemperature shutdown, and reverse-polarity protection for automotive electronics. Stable operation requires an output capacitor of at least 10 µF with ESR up to 10 Ω over the operating temperature range.
