DC650A - Demo Manual

QUICK START GUIDE FOR DEMONSTRATION CIRCUIT 650
HIGH VOLTAGE MICROPOWER LINEAR REGULATOR
LT3010
DESCRIPTION
Demonstration circuit 650 is a high voltage micropower voltage regulator using the LT3010 low dropout linear regulator, which comes in a small 8-Pin
MS8 package. DC650 has an input voltage range
from 3V to 80V and an output voltage range of 1.22V
to 60V. The circuit is capable of delivering 50mA
max.
DC650 uses low cost ceramic capacitors because the
LT3010 can maintain stability with low impedance
ceramic output capacitors. Due to its high input voltage range, the DC650 voltage regulator is ideally
suited for automotive and industrial applications.
Gerber files for this circuit are available. Call the
LTC Factory.
QUICK START PROCEDURE
Demonstration circuit 650 is easy to set up to evaluate the performance of the LT3010 high voltage micropower LDO regulator. Be careful when connecting
the test equipment to the board. High voltages are
used in the testing of this circuit. Use with caution!
Set up the circuit appropriately. Refer to figure 1 for
the proper measurement equipment setup.
3.
Increase the input voltage to 80V. Again
measure Vout; it should be 3.3V +/- 2%
(3.23V to 3.37V).
4.
Increase the load current to 50 mA. Measure
Vout again; it should be 3.3V +/- 3% (3.2V to
3.4V). When finished, set Vin to 6V and Iout
to 1 mA.
Please follow the procedure outlined below
for proper operation.
5.
Insert jumper JP1 into the OFF position and
move jumper JP2 into the 5V option (the
middle position). Re-insert jumper JP1 into
the ON position; Vout should be 5V +/- 1%
(4.95V to 5.05V). After the test, increase the
load current to 5 mA.
6.
Increase the input voltage to 80V. Again
measure Vout; it should be 5V +/- 2% (4.9V to
5.1V).
7.
Increase the load current to 50 mA. Measure
Vout again; it should be 5V +/- 3% (4.85V to
5.15V). The test is now complete.
Note of Caution: There will be high voltages in
testing this circuit. Use with caution.
1.
Before proceeding to test, insert jumper JP1
into the OFF position, and insert jumper JP2
into the 3.3V option (the lower position).
2.
Apply 4V across Vin (to GND) with 1 mA load
current. Insert jumper JP1 into the ON position. Measure Vout; it should be 3.3V +/- 1%
(3.26V to 3.34V). After the test, increase the
load current to 5 mA.
