*1. VOUT(S): Set output voltage

VOUT(E): Actual output voltage

Output voltage when fixing IOUT (= 10 mA) and inputting VOUT(S)

+ 1.0 V

*2. The output current at which the output voltage becomes 95% of VOUT(E) after gradually increasing the output current.

*3. Vdrop = VIN1

− (VOUT3 × 0.98)

VIN1 is the input voltage at which the output voltage becomes 98% of VOUT3 after gradually decreasing the input

voltage.

VOUT3 is the output voltage when VIN = VOUT(S)

+ 1.0 V and IOUT = 10 mA.

*4. A change in the temperature of the output voltage [mV/°C] is calculated using the following equation.

*2. Set output voltage

*3. Output voltage temperature coefficient

*5. Due to limitation of the power dissipation, this value may not be satisfied. Attention should be paid to the power

dissipation when the output current is large.

This specification is guaranteed by design.
