Note1: To adjust output V, differential of
in/output V must be more than 0.5V. Vin(V)-Vout(V) 0.5V
Note2: Ripple noise & efficiency are
at Vin=3.3V
Note3: Ripple noise in (_ ) is at Vin=5V
Note4: Ripple noise is measured at Bw=20MHz
Note5: Depending on ambient temperature, compulsory-air-cooling
would be needed

__- SW1 : Output off at SW1short.
__- VAR : Output V will be rating voltage at
VAR Open.
__- R1,R2 : To adjust output voltage,connect
R1 or R2 with VAR. See details in data sheet |
