    Power Management - LDO GROUP

The WL2817DA series are ultra low dropout, Low quiescent current, high PSRR CMOS LDO.

Using CMOS construction, the quiescent current consumed by the WL2817DA is typically 160 µA over the entire input voltage range, making it attractive for consumer, networking applications that demand high output current. The WL2817DA series are available in wide output voltage range version from 1.0V to 3.3V.

The WL2817DA series offer thermal shutdown (OTP) and current limit functions, to assure the stability of chip and power system at wrong condition, and it uses trimming technique to guarantee output voltage accuracy within ±2%.

The WL2817DA series can choose the output current limit between 1.0A or 500 mA by alternating the LCON pin between “H” or “L”. The WL2817DA regulators are available in DFN1612-8L packages. Standard products are Pb-free and Halogen-free.
