SKUWL2803E
The WL2803E series are ultra low dropout, low quiescent current, high PSRR CMOS LDO. The dropout voltage is 130 mV (Typ.) at 500 mA load current.
Using CMOS construction, the quiescent current consumed by the WL2803E is typically 150 uA over the entire input voltage range, making it attractive for consumer, networking applications that demand high output current. The WL2803E series are available in wide output voltage range version from 1.2V to 3.3V with 0.1V step.
The WL2803E 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 WL2803E regulators are available in SOT-23-5L packages. Standard products are Pb-free and Halogen-free.
