Description
L5150BN is a low dropout linear 5 V regulator
particularly suitable for automotive applications.
High output voltage accuracy (2%) is kept over
wide temperature range line and load variation.
Its sophisticated design allows to have extremely
low quiescent current.
The maximum input voltage is 40 V.
The regulator output current is internally limited
and the device is protected against short-circuit,
overload and overtemperature conditions. In
addition, only low-value ceramic capacitor on
output is required for stability.

Note: The curve which describes the minimum ESR is derived from characterization data on the regulator
with connected ceramic capacitors which feature low ESR values (at 100 kHz). Any capacitor with
further lower ESR than the given plot value must be evaluated in each and every case.
