LMS1585A , LMS1587 SNVS061G – MONTH 2003 – REVISED JULY 2013 www.ti.com APPLICATION NOTE OUTPUT VOLTAGE The adjustable version develops at 1.25V reference voltage, (VREF), between the output and the adjust terminal. As shown in Figure 3, this voltage is applied across resistor R1 to generate a constant current I1. This constant current then flows through R2. The resulting voltage drop across R2 adds to the reference voltage to sets the desired output voltage.
