Here is the English information on the NCP781BMN050TAG chip:

The NCP781BMN050TAG is a low quiescent current linear regulator from ON Semiconductor.

Key specifications:

• Input voltage range: 2.5V to 5.5V
• Output voltage: 5V
• Maximum output current: 50mA
• Ultra-low quiescent current: 45uA (typ)
• Short circuit current limit: 60mA (typ)
• Available in mini SOT-23 package

The NCP781BMN050TAG provides a fixed 5V output with an extremely low 45uA typical quiescent current draw, making it suitable for battery-powered devices requiring up to 50mA output current.

Integrated current limiting protection ensures safe operation.

The ultra-compact SOT-23 package maximizes space efficiency on boards.

In summary, it is an ultra-low power fixed voltage regulator ideal for precision analog circuits and other applications where quiescent current must be minimized to extend battery life.
