WL2803E

Ultra low dropout, 500mA, CMOS LDO

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.

SOT-23-5L

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%.

Pin Configuration (Top View)

The WL2803E regulators are available in SOT-23-5L

packages. Standard products are Pb-free and

Halogen-free.
