Explanation of Terms
1. I/O voltage difference (Vdif)
Vdif=VIN1−VOUT1
VOUT1:Initial output voltage
VIN1: Input voltage which generates an output voltage (VOUT2) decreased by 5 % from VOUT1
2. Load regulation (ΔVOUT2
)
ΔVOUT2=VOUT1−VOUT2
VOUT1: Output voltage when IOUT is 50 μA
VOUT2: Output voltage when IOUT is 40 mA
3. Line regulation (ΔVOUT1
)
ΔVOUT1=VOUT1−VOUT2
VOUT1: Output voltage when VIN is 24 V
OUT2: Output voltage when VIN is (VOUT+1) V
V
4. Hysteresis width (VHYS
)
VHYS=(+VDET)−(−VDET
)
+VDET: Release voltage
−VDET: Detection voltage
