QUICK START GUIDE FOR DEMONSTRATION CIRCUIT 813

HIGH VOLTAGE MICROPOWER VOLTAGE REGULATOR

LT3013

DESCRIPTION

Demonstration circuit 813 is a high voltage micro-

power voltage regulator using the LT3013 low drop-

out linear regulator, which comes in a low-profile 12-

pin DFN package. DC813 has an input voltage range

from 3V to 80V, an output voltage range between

1.24V and 60V, and is capable of delivering 250 mA

max. The DC supply current is typically only 1 uA in

shutdown. DC813 is installed with ceramic capaci-

tors, because of its ability to maintain stability with

ceramic output capacitors. Due to its high input volt-

age range, the DC813 voltage regulator is ideally

suited for automotive and industrial applications.

Design files for this circuit board are available. Call

QUICK START PROCEDURE

DC813 is easy to set up to evaluate the performance

of the LT3013. For proper measurement equipment

configuration, set up the circuit according to the dia-

gram in Figure 1.

Please follow the procedure outlined below for proper

operation.

1. Before proceeding to test, insert a shunt into

the OFF position of jumper JP1, and insert a

shunt into jumper JP2, the 3.3V option.

2. Apply 5V across Vin (to GND). Insert the

jumper JP1 shunt into the ON position. Draw

1 mA of load current. Measure Vout; it should

be 3.3V +/- 2.5% (3.21V to 3.39V).

3. Vary the input voltage from 5V to 80V and the

load current from no load to 250 mA. Vout

should measure 3.3V +/- 5% (3.13V to

3.47V).

Note: Be aware of the power dissipated by the

LT3013, due to its high input voltage capabil-

ity. Consequently, take care to stay under the

maximum junction temperature, 125 deg.C,

when operating the LT3013.

4. Insert the jumper JP1 shunt into the OFF posi-

tion and move the shunt in jumper JP2 into

the 5V output voltage option, and repeat the

test. Re-insert jumper JP1 shunt into the ON

position. Just as in the 3.3 Vout test, the 5V

output voltage should read Vout +/- 2.5% tol-

erance under static line and load conditions,

and +/- 5% tolerance under dynamic line and

load conditions.

5. When finished evaluating, insert jumper JP1

shunt into the OFF position.

Warning - If long leads are used to power the demo circuit, the input voltage at the part could “ring”. This ring-

ing could affect the operation of the circuit or even exceed the maximum voltage rating of the IC. To eliminate

this, insert a small aluminum electrolytic capacitor (for instance, a Sanyo cap., part # 100CV10BS) on the pads

between the input power and return terminals on the bottom of the demo board. The (greater) ESR of the alu-

minum electrolytic capacitor will dampen the (possible) ringing voltage due to the use of long input leads. On a

normal, typical PCB, with short traces, the capacitor is not needed.
