WL2803E
Ultra low dropout, 500mA, CMOS LDO
WL2803E
Http://www.sh-willsemi.com
Descriptions
The WL2803E series are ultra low dropout, Low
quiescent current, high PSRR CMOS LDO. The
dropout voltage is 130mV (Typ.) at 500mA load
current.
Using CMOS construction, the quiescent current
consumed by the WL2803E is typically 150uA 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%.
