APPLICATION CIRCUIT OF FIXED/FIXED VERSION
APPLICATION CIRCUIT OF FIXED/ADJ VERSION
NOTE: The regulator is designed to be stable with either tantalum or ceramic capacitors on the input and outputs. The expected values of
the input and output X7R ceramic capacitors are from 4.7F to 22F with 4.7F typical. The input capacitor must be connected within 0.5
inches of the VI terminal. The output capacitors must also be connected within 0.5 inches of output pins VO1 and VO2. There is no upper limit
to the size of the input capacitor (for more details see the Application Hints section).
NOTE: In the Fixed/ADJ version, the adjustable output voltage VO2 is designed to support output voltages from 1.25V to VI -VDROP.The
adjustable output voltage VO2 is set by a resistor divider connected between VO2 (pin4) and Ground (pin3) with its centre tap connected to
VO2 ADJ (pin2). The voltage divider resistors are: R1 connected to VO2 and VO2 ADJ and R2 connected to VO2 ADJ and GND. VO2 is deter-
mined by VREF,R1,R2, and IADJ as follows (for more details see the Application Hints section):
VO2 =VREF (1+R1/R2)+ IADJR1
