HT78XX General Description

The HT78XX series of positive,linear regulators feature slow quies cent current (5Atyp.)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 from1.8V 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 haveThermal Shut down and Current Limiting to prevent device failure under the "Worst" of operating conditions.

HT78XX Maximum Ratings

Maximum Supply Voltage............................up to 8.5V
Operating Temperature.........................40C to 85C
Storage Temperature..........................50C to 125C

Note:These are stress ratings only.Stresses exceeding the range specified under Absolute Maximum Ratings may cause substantial damage to the device.Functional operation of this device at other conditions beyond those listed in the specification is not impliedand prolonged exposure to extreme conditions may affect device reliability.

*Absolute maximum ratings indicate limits beyond which damage to the device may occur.Operating Ratings indicate conditions for which the device is intended to be functional,but do not guarantee specific performance limits.The guaranteed specifications apply only for the test conditions listed.
