Note 1: “Absolute Maximum Ratings” indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is
intended to be functional, but do not guarantee specific performance limits. For guaranteed specifications and test conditions, see Electrical Characteristics. The
guaranteed specifications apply only for the test conditions listed. Some performance characteristics may degrade when the device is not operated under the listed
test conditions.
Note 2: Without PCB copper enhancements. The maximum power dissipation must be de-rated at elevated temperatures and is limited by T

Note 3: The human body model is a 100 pF capacitor discharged through a 1.5 kΩ resistor into each pin. The machine model is a 200 pF capacitor discharged
directly into each pin.
Note 4: Typical numbers are at 25˚C and represent the most likely parametric norm.
Note 5: Limits are 100% production tested at 25˚C. Limits over the operating temperature range are guaranteed through correlation using Statistical Quality Control
(SQC) methods. The limits are used to calculate National’s Averaging Outgoing Quality Level (AOQL).

Note 7: Thermal hysteresis is defined as the change in +25˚C output voltage before and after exposing the device to temperature extremes.
Note 8: Output noise voltage is proportional to V . V for other voltage option is calculated using (V /1.8) * V . V (2.5V) = (36µV /1.8) * 2.5 = 46µV .

must be taken close to GND to turn the part off (see spec.
table for thresholds). There is a minimum slew rate on this
pin of about 0.003V/µS to prevent glitches on the output. All
of these conditions can easily be met with ordinary CMOS or
TTL logic. If the shutdown feature is not required, then this
pin can safely be connected directly to the input supply.
Floating this pin is not recommended.
Pin Functions
Output (Pin 5): Reference Output.
Input (Pin 4):Positive Supply.
Ground (Pin 2):Negative Supply or Ground Connection.
Enable (Pin 3):Pulled to input for normal operation. Forcing
this pin to ground will turn-off the output.
REF (Pin 1):REF Pin. This pin should be left unconnected.
Application Hints
The standard application circuit for the LM4120 is shown in
Figure 1. It is designed to be stable with ceramic output
capacitors in the range of 0.022µF to 0.047µF. Note that
0.022µF is the minimum required output capacitor. These
capacitors typically have an ESR of about 0.1 to 0.5Ω.
Smaller ESR can be tolerated, however larger ESR can not.
The output capacitor can be increased to improve load tran-
sient response, up to about 1µF. However, values above
0.047µF must be tantalum. With tantalum capacitors, in the
1µF range, a small capacitor between the output and the
reference pin is required. This capacitor will typically be in
the 50pF range. Care must be taken when using output
capacitors of 1µF or larger. These application must be thor-
oughly tested over temperature, line and load.
10104732
FIGURE 1.
INPUT CAPACITOR
Noise on the power-supply input can effect the output noise,
but can be reduced by using an optional bypass capacitor
between the input pin and the ground.
An input capacitor is typically not required. However, a 0.1µF
ceramic can be used to help prevent line transients from
entering the LM4120. Larger input capacitors should be
tantalum or aluminium.
PRINTED CIRCUIT BOARD LAYOUT CONSIDERATION
The mechanical stress due to PC board mounting can cause
the output voltage to shift from its initial value. References in
SOT packages are generally less prone to assembly stress
than devices in Small Outline (SOIC) package.
The reference pin is sensitive to noise, and capacitive load-
ing. Therefore, the PCB layout should isolate this pin as
much as possible.
To reduce the stress-related output voltage shifts, mount the
reference on the low flex areas of the PC board such as near
to the edge or the corner of the PC board.
The enable pin is an analog input with very little hysteresis.
About 6µA into this pin is required to turn the part on, and it
