Pin Functions
V
can source up to 20 mA. It is stable with output capacitor
ranges from 0 to 100 µF.
V
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 100 µF.
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 be-
cause 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
respectively.
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) pack-
age.
To minimize the mechanical stress due to PC board mount-
ing 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.
