ST’s new L5 series of automotive voltage regulators comply with the latest automotive standards for line disturbance, noise rejection.  The L5 series offers a stable output voltage of 5 V with a 2% tolerance throughout a wide range of operative conditions and a significantly lower leakage to GND current (typical quiescent current of 5 µA). This series offers products with output current of 150 mA (L5150 series) and 300 mA (L5300 series). Each product has embedded features such as reset, enable, early warning, short-circuit protection and thermal shut-down.  A main benefit of the L5 series is that it only requires a low-value ceramic capacitor (Co = 220 nF) for output stability.
