    Power Management - LDO GROUP

The WL2817S series are ultra low dropout, Low quiescent current, high PSRR CMOS LDO.

Using CMOS construction, the quiescent current consumed by the WL2817S is typically 160uA over the entire input voltage range, making it attractive for appliciations that demand high output current.

To assure the stability of chip and power system at wrong condition, the WL2817S series offer thermal shutdown (OTP) and current limit functions. They are also use trimming technique to guarantee output voltage accuracy within ±2 (VOUT≥2V).

The WL2817S regulators are available in SOP-8L-EP packages. Standard products are Pb-free and Halogen-free.
