HT72xx中文资料300mA TinyPower™ LDO数据手册Holtek规格书

描述 Description

(TO92 Package 产品终止信息 -- 最后订单日 : 2014/11/03 生产停止日 : 2015/02/03)The HT72xx series of positive, linear regulators features low quiescent current (4mA typ.) with low dropout voltage, making them ideal for batteryapplications. The space-saving 3-pin 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.
