NCP59150, NCV59150 Series
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 V
OUT
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 (125C). The P
D
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.

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.
