Conditions
*1: IS1 is specified at the 5% drop point of output voltage VO on the condition that VIN = overcurrent protection starting current, IO = 10 mA.
*2: Output is OFF when the output control terminal (VC terminal) is open. Each input level is equivalent to LS-TTL level. Therefore, the device can be driven directly by LS-TTLs.

R1
SI-3010LLSL is designed to use a low ESR capacitor (such as
a ceramic capacitor) for the output capacitor. The recom-
mended ESR value for an output capacitor is 500mΩ or less
(at room temperature).
