1.24 V / R2, and the current in R1 is the current in R2 plus

the ADJ pin bias current. The ADJ pin bias current flows

from VOUT through R1 into the ADJ pin.

The output voltage can be calculated using the formula

shown in Figure 23.

Thermal Considerations

The power handling capability of the device is limited by

the maximum rated junction temperature (125C). The PD

total power dissipated by the device has two components,

Input to output voltage differential multiplied by Output

current and Input voltage multiplied by GND pin current.

PD + VIN * VOUT @ IOUT ) VIN @ IGND (eq. 1)

The GND pin current value can be found in Electrical

Characteristics table and in Typical Characteristics graphs.

The Junction temperature TJ is

TJ + TA ) PD @ RqJA

(eq. 2)

where TA is ambient temperature and RqJA is the Junction to

Ambient Thermal Resistance of the NCP/NCV59150

device mounted on the specific PCB.

To maximize efficiency of the application and minimize

thermal power dissipation of the device it is convenient to

use the Input to output voltage differential as low as possible.

The static typical dropout characteristics for various

output voltage and output current can be found in the Typical

Characteristics graphs.
