LM78MXXM3

CYStek Product Specification

Three Terminal Medium Current Positive

Voltage Regulators

LM78MXXM3

Description

The LM78MXXM3 series of three-terminal positive regulators are available in the SOT-89 package and with 5V, 6V,

8V, 9V, 12V, 15V, 18V and 24V fixed output

voltages, making them 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 them essentially indestructible. If adequate heat sinking is provided, they

can be used with external components to obtain adjustable voltages and currents.
