 Description
The DIO1266B features a low- RON internal FET and
an operating range of 2.5 VDC to 40 VDC (absolute
maximum of 42 VDC). The DIO1266B features
overvoltage protection that powers down the internal
FET if the input voltage exceeds the OVP threshold.
The OVP threshold is adjustable with optional
external resistors. Overtemperature protection also
powers down the device at 130°C (Typ.).
The DIO1266B is available in WLCSP-12 package. It
is specified over ambient temperature range of -40°C
to 85°C.It can be used in a wide range of applications
such as mobile phones and tablets.
