AUTOMOTIVE, 125°C OPERATION, 36 V INPUT, 250 mA VOLTAGE REGULATOR

Rev.5.3_00

S-19212B/DxxA Series

13



Explanation of Terms

1. Low dropout voltage regulator

This is a voltage regulator which made dropout voltage small by its built-in low on-resistance output transistor.

2. Output voltage (VOUT)

This voltage is output at an accuracy of

±2.0% when the input voltage, the output current and the temperature are

in a certain condition*1.

*1. Differs depending on the product.

Caution

If the certain condition is not satisfied, the output voltage may exceed the accuracy range of

±2.0%.

Refer to " Electrical Characteristics" and " Characteristics (Typical Data)" for details.

3. Line regulation 

ΔVOUT1

ΔVIN • VOUT

Indicates the dependency of the output voltage against the input voltage. That is, the value shows how much the

output voltage changes due to a change in the input voltage after fixing output current constant.

4. Load regulation (

ΔVOUT2)

Indicates the dependency of the output voltage against the output current. That is, the value shows how much the

output voltage changes due to a change in the output current after fixing input voltage constant.

5. Dropout voltage (Vdrop)

Indicates the difference between input voltage (VIN1) and the output voltage when the output voltage becomes 98%

of the output voltage value (VOUT3) at VIN = VOUT(S)

+ 2.0 V after the input voltage (VIN) is decreased gradually.

Vdrop = VIN1

− (VOUT3 × 0.98)
