General Description

The HT78XX series of positive, linear regulators fea-

tures low quiescent current (5

mA typ.) with low dropout

voltage, making them ideal for battery applications. The

devices are capable of supplying 500mA of output cur-

rent continuously.

They are available with several fixed output voltages

ranging from 1.8V to 5.0V. Although designed primarily

as fixed voltage regulators, these devices can be used

with external components to obtain variable voltages

and currents.

These rugged devices have Thermal Shutdown and

Current Limiting to prevent device failure under the

²Worst² of operating conditions.
