SM78Lxx Series
Elektronische Bauelemente
Positive Voltage Regulator
RoHS Compliant Product
A suffix of “-C” specifies halogen or lead -free
DESCRIPTION
The SM78LXX-B series of positive regulators are
available in the SOT-89 package and with 5V, 6V, 8V, 9V,
10V, 12V, 15V and 18V fixed output voltages, making it
useful in a wide range of applications. These regulators
can provide local on-card regulation, eliminating the
distribution problems associated with single point regulation.
Each type employs internal current limiting, thermal shut-down
and safe operating area protection, making it essentially
indestructible. If adequate heat sinking is provided, they
can deliver over 100mA output current. Although designed
primarily as fixed voltage regulators, these devices can
be used with external components to obtain adjustable
voltages and currents. SM78Lxx is characterized for
operation from 0°C to +125°C.
