Ultra low dropout, 500mA, CMOS LDO

Descriptions

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.

SOP-8L-EP

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%(V_OUT≥2V).

The WL2817S regulators are available in SOP-8L-EP

packages. Standard products are Pb-free and

Halogen-free.
