HIP5600
Application Information
Introduction
In many electronic systems the components operate at 3V to
15V but the system obtains power from a high voltage
source (AC or DC). When the current requirements are
small, less than 10mA, a linear regulator may be the best
supply provided that it is easy to design in, reliable, low cost
and compact. The HIP5600 is similar to other 3 terminal reg-
ulators but operates from much higher voltages. It protects
its load from surges
+250V
above its 400V operating input
voltage and has short circuit current limiting and thermal
shutdown self protection features.
Output Voltage
The HIP5600 provides a temperature independent 1.18V
reference, V
REF
, between the output and the adjustment
terminal (V
REF
= V
OUT
- V
ADJ
). This constant reference
voltage is impressed across RF1 (see Figure 2) and results
in a constant current (I
1
) that flows through RF2 to ground.
The voltage across RF2 is the product of its resistance and
the sum of I
1
and I
ADJ.
The output voltage is given in Equa-
tions 1(A, B).
