... The ADJ pin bias current, 1.3μA at 25°C, fl ows through R2 into the ADJ pin. Use the formula in Figure 2 to calcu- late output voltage. Linear Technology recommends that R1’s value be less than 12.1k to minimize output voltage errors due to the ADJ pin bias current. In shutdown, the output turns off and the divider current is zero ...
