500-mA LOW-NOISE LOW-DROPOUT VOLTAGE REGULATOR
WITH SHUTDOWN
SLVS581 – SEPTEMBER 2006
APPLICATION INFORMATION (continued)
If the application is not too sensitive to regulator overshoot, both the output capacitor and bypass capacitor (if
applicable) can be reduced.
Adjustable Output Version
For the adjustable version, the output voltage is set by two external resistors forming a voltage divider connected
to the output and the ADJ pin (see Figure 7). V_OUT is set based on the equation:
V_OUT = 1.242 V(1 + R2/R1)
Although ADJ represents a high-impedance input, limit R2 to ≤ 470 kΩ for optimum performance.
