Notes: 1. Above 25°C derate by 8.3mW/°C
2. Allowable temperature of IC junction part, Tj (max), is as shown below.
Tj (max) = θj - a • Pc (max)+Ta
(θj - a is thermal resistance value during mounting, and Pc (max) is the maximum value of IC
power dissipation.)
Therefore, to keep Tj (max) ≤ 125°C, wiring density and board material must be selected
according to the board thermal conductivity ratio shown below.

Low Voltage (2 to 7 V) Regulator: Figure 1 shows the construction of a basic low voltage regulator. The
divider (resistors R1 and R2) from V
noninverted input of the error amplifier, less than output voltage. In the fixed voltage source where the
output voltage will be fed back to the error amplifier directly as shown in figure 1. Output voltage will be
divided VREF since the output voltage is equal to the reference voltage.

Negative Voltage Regulator: Figure 3 shows the construction of a so-called negative voltage regulator,
which generates a negative output voltage with regard to GND. Assume that the output voltage, –V
increases in the negative direction. As the voltage across the R1 is larger than that across the R3, which
provides the reference voltage, the output current of the error amplifier increases. In the control circuit, the
impedance decreases with the increase of input current, which makes the base current of the external
transistor Q approach GND. As a result, the output voltage returns to the established value and output
voltage is stable.
