SM78Lxx
Elektronische Bauelemente
Positive Voltage Regulator
RoHS Compliant Product
A suffix of “-C” specifies halogen or lead -free
DESCRIPTION
The SM78LXX series of positive regulators are available in the SOT-89 package and with 5V, 6V, 8V, 9V, 10V, 12V,
15V, 18V and 24V 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.
FEATURES
Internal Short-Circuit Current Limiting
