Introduction
The WL2803K series are ultra low dropout, Low quiescent current, high PSRR CMOS LDO. The dropout voltage is 260mV (Typ.) at 800mA load current. Using CMOS construction, the quiescent current consumed by the WL2803K is typically 150uA over the entire input voltage range, making it attractive for consumer, networking applications that demand high output current. The WL2803K series are available in wide output voltage range version from 1.2V to 3.3V with 0.1V step. Standard output voltages are 1.8V, 3.3V. Other output voltage options are available upon request. The WL2803K 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 WL2803K regulators are available in SOT-89-5L packages. Standard products are Pb-free and Halogen-free.
