Here is the English information on the NCP81071BDR2G chip:

The NCP81071BDR2G is a low quiescent current linear regulator from ON Semiconductor.

Key specifications include:

• Input voltage range: 2.5V to 5.5V
• Output voltage: 1.8V
• Maximum output current: 100mA
• Ultra-low quiescent current: 50uA (typ)
• Short circuit current limit: 110mA (typ)
• Available in miniature DFN3x3 package

The NCP81071BDR2G provides a fixed 1.8V output with an extremely low 50uA typical quiescent current draw.

Its ultra-low operational power consumption makes this regulator well-suited for battery-powered devices requiring up to 100mA output.

In-built current limiting protection helps ensure safe operation.

The compact DFN package maximizes board space efficiency.

In summary, it is an ultra-low power fixed LDO voltage regulator ideally suited for precision analog circuits and other applications where quiescent current is critical to battery lifetime.
