Holtek Semiconductor HT78R30B
The HT78Rxx series of positive, linear regulators feature low quiescent current (3µA typ.) with low dropout voltage, making them ideal for battery applications. The space-saving 5-pin SOT23 package is attractive for “Pocket” and “Hand Held” applications. The devices are capable of supplying 500mA of output current continuously.| Part No. | HT78R30B |

GENERAL DESCRIPTION
They are available with several fixed output voltages ranging from 1.5V 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.
