Ultra low dropout, 500mA/1A, CMOS LDO
The WL2817 series are ultra low dropout, Low
quiescent current, high PSRR CMOS LDO.
Using CMOS construction, the quiescent current
consumed by the WL2817 is typically 160uA over the
entire input voltage range, making it attractive for
consumer, networking applications that demand high
output current. The WL2817 series are available in
wide output voltage range version from 1.0V to 3.3V.
The WL2817 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 WL2817 series can choose the output current limit
between 1.0A or 500mA by alternating the LCON pin
between “H” or “L”.
