Formula of Output Voltage Adjustment
VOUT = VADJ (≈1.25V) × (R1+R2)/R1
Note: Set the resistance of R1 and R2 so that a large enough current flows through the two resistors, making the effect
on the source current from the ADJ pin negligible.
Startup Method
This IC can be started in one of the following two ways:
(1) Start the IC by turning on and off the EN pin after applying power to VCC1 and VCC2.
(2) Short-circuit the VCC1, VCC2, and EN pins.
When using method (1), apply power to VCC1 and VCC2 simultaneously, or in the order of VCC1 to VCC2, then to
the EN pin.
To shutdown the IC, follow the start-up procedure in reverse order.
