LR1812数据手册UTC中文资料规格书

描述 Description

The UTC LR1812 operate from a +1.5V ~ +6V input supply as fast ultra low-dropout linear regulators. Wide output voltage range options are available. The fast  response characteristic to make UTC LR1812 suitable for low voltage microprocessor application.The low quiescent current operation and low dropout quality caused by the CMOS process. The UTC  LR1812 has low dropout voltage. The ground pin current is typically 60uA. Output Voltage Precision: Multiple output voltage options are available and ranging from 1.2V ~ 5.0V at room temperature with a guaranteed accuracy of ±1.5%, and ±3.0% when varying line andload.  With the reverse current protection function of a driver transistor, the reverse current  flow is prohibited when VOUT voltage is higher than VIN voltage. For an example, when a battery is connected to the VOUT pin, battery current will not flow back to the UTC LR1812 The output voltage types of UTC LR1812-xx  are fixed one in the IC.
