General Description

The HT72XX series of positive, linear regulators fea-

tures low quiescent current (5mA typ.) with low dropout

voltage, making them ideal for battery applications. The

space-saving SOT-23 package is attractive for ²Pocket²

and ²Hand Held² applications. The devices are capable

of supplying 300mA of output current 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.
