L5050S 5 V low drop linear voltage regulator for automotive application Datasheet - production data Enable input for enabling/disabling the voltage regulator Thermal shutdown and short circuit protection Wide temperature range (T = -40C to 150C) j 62 Description The L5050S is a 5 V low dropout linear voltage regulator suitable for automotive applications, Features available in a SO-8 package. The LDO delivers up to 50 mA of load current, and consumes as low as 5 A of quiescent current with device disabled. Max DC supply voltage V 40 V S High output voltage accuracy (2%) is kept over Max output voltage tolerance V +/-2% wide temperature range, line and load variation. o Enable feature allows output enabling or Max dropout voltage Vdp 500 mV disabling. The maximum input voltage is 40 V. Output current Io 50 mA The regulator output current is internally limited (1) and the device is protected against short circuit, Quiescent current Iqn 5 A overload and over temperature conditions. In 1. Typical value valid with En=LOW. addition, only low value ceramic capacitor on output is required for stability. AEC-Q100 qualified Operating DC supply voltage range 5.6 V to 40 V Low dropout voltage Low quiescent current consumption Precision output voltage 5 V 2% Table 1.
