LM4040

Precision micropower shunt voltage references

Description

The LM4040 is a family of bandgap circuits Excellent performance is maintained over the

designed to achieve precision micro-power 60µA to 15mA operating current range with a

voltage references of 2.5V, 3.0V and 5.0V. The typical temperature coefficient of only 20ppm/°C.

devices are available in 0.2% B-grade, 0.5% C- The device has been designed to be highly

grade and 1% D-grade initial tolerances.

tolerant of capacitive loads so maintaining

excellent stability.

They are available in small outline SOT23 and

SC75 surface mount package which are ideal This device offers a pin for pin compatible

for applications where space saving is alternative to the LM4040 voltage reference. The

important.

LM4040 is also available with AEC-Q100

approval; see LM4040Q datasheet

Application information

In a conventional shunt regulator application, an external series resistor (R ) is

S

connected between the supply voltage, V , and the LM4040

S

V_S

R determines the current that flows through the load (I ) and the LM4040 (I ).

S

L

R

I_R+

I_L

Since load current and supply voltage may vary, R should be small enough to

S

supply at least the minimum acceptable I to the LM4040 even when the supply

R

R_S

voltage is at its minimum and the load current is at its maximum value. When

I_L

the supply voltage is at its maximum and I is at its minimum, R should be

L

S

large enough so that the current flowing through the LM4040 is less than 15 mA.

V_R

I_R

R is determined by the supply voltage, (V ), the load and operating current, (I

and I ), and the LM4040’s reverse breakdown voltage, V .

Printed circuit board layout considerations

LM4040s in the SOT23 package have the die attached to pin 1, which results in an electrical

contact between pin 2 and pin 3. Therefore, pin 1 of the SOT-23 package must be left floating or

connected to pin 2.

LM4040s in the SC75 package have the die attached to pin 2, which results in an electrical contact

between pin 2 and pin 1. Therefore, pin 2 must be left floating or connected to pin1.
