com General Description The HT78XX series of positive, linear regulators features low quiescent current (5mA 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.
