LM4130
Precision Micropower Low Dropout Voltage Reference

LM4130 Precision Micropower Low Dropout Voltage Reference

General Description

The LM4130 family of precision voltage references performs
comparable to thebestlaser-trimmed bipolar references, but
in cost effective CMOS technology. Key to this break through
is the use of EEPROM registers for correction of curvature,
tempco, and accuracy on a CMOS bandgap architecture that
allows package level programming to overcome assembly
shift. The shifts in voltage accuracy and tempco during as­sembly of die into plastic packages limit the accuracy of ref­erences trimmed with laser techniques.

Unlike other LDO references, the LM4130 requires no output
capacitor. Neither is a buffer amplifier required, even with
loads up to 20mA. These advantages and the SOT23 pack­aging are important for cost-critical and space-critical appli­cations.

Series references provide lower power consumption than
shunt references, since they don’t have to idle the maximum
possible load current under no load conditions. This advan­tage, the low quiescent current (75µA), and the low dropout
voltage(275mV) make the LM4130 ideal for battery-powered
solutions.

The LM4130 is available in five grades (A, B, C, D and E) for
greater flexibility. The best grade devices (A) have an initial
accuracy of 0.05%with guaranteed temperature coefficient
of 10ppm/˚C or less, while the lowest grade parts (E) have
an initial accuracy of 0.5%and a tempco of 30ppm/˚C.

Pin Functions

(Pin 5): Reference Output. The output of the LM4130

REF

LM4130

can source up to 20 mA. It is stable with output capacitor
ranges from 0 to 100 µF.

V

(Pin 4):Positive Supply. Bypassing with a 0.1µF capaci-

IN

tor is recommended if the output loading changes or input is
noisy.

Ground (Pin 2):Negative Supply or Ground Connection.
NC (Pins 1, 3):No Connection (internally terminated). These

pins must be left unconnected.

Application Information

Output Capacitor

The LM4130 is designed to operate with or without an output
capacitor and is stable with capacitive loads of up to 100µF.

Connecting a capacitor between the output and ground will
significantly improve the load transient response when
switching from a light load to a heavy load. However, the out­put capacitor should not be made arbitrarily large because it
will effect the turn-on time as well as line and load transients.

Input Capacitor

A small 0.1µF capacitor on the input significantly improves
stability under a wide range of load conditions. With an input
bypass capacitor, the LM4130 will drive any combination of
resistance and capacitance up to V
spectively.

/20mA and 100µF re-

REF

Noise on the power-supply input can effect the output noise,
but it can be reduced by using an optional bypass capacitor
between the input pin and the ground.

Printed Circuit Board Layout Consideration

References in SOT packages are generally less prone to as­sembly stress than devices in Small Outline (SOIC) pack­age.

To minimize the mechanical stress due to PC board mount­ing that can cause the output voltage to shift from its initial
value, mount the reference on a low flex area of the PC
board, such as near the edge or a corner.
