HT78XX -- 500mA TinyPowerTM LDO
General Description
The HT78XX series of positive, linear regulators features
low quiescent current (4mA typ.) with low dropout
voltage, making them ideal for battery applications. The devices are capable of supplying 500mA 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
"Worst" of operating conditions.
