HIGH-PRECISION VOLTAGE REGULATOR

S-812XXSG Series

Technical Terms

1 Output voltage (VOUT)

The precision of output voltage is guaranteed at ±2.0% or ±2.4% under the prescribed conditions of input voltage,

output voltage, and temperature, which differ with items. If these conditions are varied, output voltage value may

change into beyond the scope of precision of output voltage. See electrical characteristics and characteristics

data for detail.

2 Line regulations 1 and 2 (
VOUT1,
VOUT2)

Indicates the input voltage dependencies of output voltage. That is, the values express how the output voltage

changes, when input voltage is changed under the condition that output current is fixed.

3 Load regulation (
VOUT3)

Indicates the output current dependencies of output voltage. That is, the values express how the output voltage

changes, when output current is changed under the condition that input voltage is fixed.

4 I/O voltage defference (Vdif)

98% of VOUT is output when the voltage of VOUT+Vdif is applied. When Vdif is small, output keeps a constant

voltage in the small side of input voltage and large output current can be obtained.

NOTE : Vdif is highly dependent on IOUT.
