DESCRIPTION
The SPX3819 is a positive voltage regulator with a low dropout voltage and low noise output. In
addition, this device offers a very low ground current of 800µA at 100mA output. The SPX3819 has
an initial tolerance of less than 1% max and a logic compatible ON/OFF switched input. When
disabled, power consumption drops to nearly zero. Other key features include reverse battery
protection, current limit, and thermal shutdown. The SPX3819 includes a reference bypass pin for
optimal low noise output performance. With its very low output temperature coefficient, this device
also makes a superior low power voltage reference.
The SPX3819 is an excellent choice for use in battery-powered applications such as cordless
telephones, radio control systems, and portable computers. It is available in several fixed voltages
-- 1.2V, 1.5V, 1.8V, 2.5V, 3.0V, 3.1V, 3.3V, 5.0V -- or with an adjustable output. This device is offered
in 8 pin NSOIC, 8 pin DFN and 5-pin SOT-23 packages.

NOTES
Note 1: The maximum allowable power dissipation is a function of maximum operating junction temperature, TJ(max) the junction to ambient thermal
resistance, and the ambient θJA, and the ambient temperature TA. The maximum allowable power dissipation at any ambient temperature is
given: PD(max) = (TJ(max)-TA)/θJA, exceeding the maximum allowable power limit will result in excessive die temperature; thus, the regulator will
go into thermal shutdown. The θJA of the SPX3819 is 220°C/W mounted on a PC board.
Note 2: Not applicable to output voltage 2V or less.

APPLICATION INFORMATION
The SPX3819 requires an output capacitor for
device stability. Its value depends upon the
application circuit. In general, linear regulator
stability decreases with higher output currents.
In applications where the SPX3819 is sourcing
less current, a lower output capacitance may be
sufficient. For example, a regulator outputting
only 10mA, requires approximately half the
capacitance as the same regulator sourcing
150mA.
concern. The SPX3819 start-up speed is in-
versely proportional to the size of the BYP
capacitor. Applications requiring a slow ramp-
up of the output voltage should use a larger
CBYP. However, if a rapid turn-on is necessary,
the BYP capacitor can be omitted.
The SPX3819’s internal reference is available
through the BYP pin.
Benchtestingisthebestmethodfordetermining
the proper type and value of the capacitor since
the high frequency characteristics of electro-
lytic capacitors vary widely, depending on type
and manufacturer. A high quality 2.2µF alumi-
num electrolytic capacitor works in most appli-
cation circuits, but the same stability often can
be obtained with a 1µF tantalum electrolytic.
Figure 1 represents a SPX3819 standard appli-
cation circuit. The EN (enable) pin is pulled
high (>2.0V) to enable the regulator.
To disable the regulator, EN < 0.4V.
The SPX3819 in Figure 2 illustrates a typical
adjustable output voltage configuration. Two
resistors (R1 and R2) set the output voltage. The
output voltage is calculated using the formula:
With the SPX3819 adjustable version, the mini-
mumvalueofoutputcapacitanceisafunctionof
the output voltage. The value decreases with
higher output voltages, since closed loop gain is
increased.
VOUT = 1.235V x [ 1 + R1/R2]
R2 must be > 10 kΩ and for best results, R2
shouldbebetween22kΩand47kΩ. Acapacitor
placed between ADJ and Ground will provide
improved noise performance.
Typical Applications Circuits
A 10nF capacitor on the BYP pin will signifi-
cantly reduce output noise, but it may be left
unconnected if the output noise is not a major
