Ultra low dropout, 800mA, CMOS LDO
The WL2803D series are ultra low dropout, Low
quiescent current, high PSRR CMOS LDO.
Using CMOS construction, the quiescent current
consumed by the WL2803D is typically 150uA over the
entire input voltage range, making it attractive for
consumer, networking applications that demand high
output current. The WL2803D series are available in
wide output voltage range version from 1.2V to 3.3V.
The WL2803D 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 WL2803D regulators are available in DFN2X2-6L
packages. Standard products are Pb-free and
