WL2861K
High Input Voltage, Low Quiescent Current
LDO
Descriptions
The WL2861K series is a high accuracy, high input
voltage low quiescent current, high speed, and low
dropout Liner regulator with high ripple rejection. The
device is manufactured with Bi-CMOS process.
The WL2861K offers over-current limit and over
temperature protection to ensure the device working in
well conditions.
The WL2861K regulators are available in standard
SOT-89-3L packages. Standard products are Pb-free
and Halogen-free.
