HT7233中文资料300mA TinyPower™ LDO数据手册Holtek规格书

描述 Description

The HT72xx series of positive, linear regulators features low quiescent current (4mA typ.) with low dropout voltage, making them ideal for battery applications. The space-saving SOT23 package is attractive for \"Pocket\" and \"Hand Held\" 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 \"Worst\" of operating conditions.
