DESCRIPTION
The SP6222 and SP6223 are CMOS LDOs designed to meet a broad range of applications that require accuracy,
speed and ease of use. These LDOs offer extremely low quiescent current which only increases slightly under load,
thus providing advantages in ground current performance over bipolar LDOs. The LDOs handle an extremely wide
load range and guarantee stability with a 1μF ceramic output capacitor. They have excellent low frequency PSRR,
not found in other CMOS LDOs and thus offer exceptional Line Regulation. High frequency PSRR is 55dB (typical)
at 1kHz. Load Regulation is excellent and temperature stability is comparable to bipolar LDOs. An enable feature
is provided on all versions. The SP6222/6223 is available in fixed and adjustable output voltage versions in
industry standard SC70 and SOT23 packages.

APPLICATION INFORMATION
General Overview
Input / Output Capacitor
The SP6222 and SP6223 are CMOS
LDOs designed to meet a broad range
of low voltage applications that require
accuracy and ease of use. The
SP6222 offers a 50mA output current
while the SP6223 offers an output
current of 150mA. The SP6222 is
available in a 2.5V or 3.0V fixed output
along with an adjustable output
version. The SP6223 is offered in an
adjustable output only. These LDOs
have a minimum input voltage of only
1.6V and a maximum input voltage of
4.5V. The output voltage can be
programmed to as low as 0.9V and
have a maximum dropout voltage
rating of 100mV for the SP6222 and
300mV for the SP6223. Both devices
are equipped with an enable (EN)
input for very low current (10nA typical)
shutdown mode.
The SP6222/6223 is designed to
operate using very small ceramic
capacitors. The minimum input and
output capacitor value for stable
operation is 1.0μF. The output
capacitor value may be increased
without limit to improve transient
response. Place these capacitors
as close as possible to the device.
Bypass (BYP) Capacitor
The fixed output versions offer a
BYP pin to decouple the bandgap
reference. Connecting an external
10nF capacitor from BYP to GND
can reduce output noise. If output
noise is not a concern the BYP pin
may be left open. When a bypass
capacitor is used the turn on time is
slower. See the following turn on
time plots for various BYP capacitor
values. The adjustable output
version does not offer this BYP input.
Enable / Shutdown Operation
Adjustable Regulator
The SP6222/6223 is turned on by
providing 1.6V or greater to the EN
pin. To place the device into shutdown
pull the EN pin below 0.4V. If this
feature is not required connect EN to
input supply to always enable the
device whenever power is applied.
Oct17-06 Rev AC
The output of the device can be
programmed to a specific voltage by
using two external resistors
connected to the ADJ pin (see
Typical Application Circuit for
Adjustable output). The resistors set
SP6222/6223 50/150mA CMOS Linear Regulators

APPLICATION INFORMATION
The actual power dissipation of the
regulator circuit can be determined
by using the simplified equation:
the output voltage based on the
following equation:
VOUT = VREF *(R1/R2 + 1)
PD = (VIN – VOUT) * IOUT
Resistor values are not critical
because the ADJ (adjust) pin has a
high impedance, but for best
performance use resistor values of
470KΩ or less.
To prevent the device from entering
thermal shutdown, maximum power
dissipation cannot be exceeded.
Layout Considerations
The primary path of heat conduction
out of the package is via the package
leads. Therefore, careful consideration
must be taken into account for
optimizing layout.
Thermal Considerations
The SP6222/6223 is designed to
provide 50mA -150mA of continuous
current in a tiny package. Maximum
power dissipation can be calculated
based on the output current and the
voltage drop across the part. To
determine the maximum power
dissipation of the package, use the
junction-to-ambient
thermal
resistance of the device and the
following equation:
1. Attaching the part to a large
copper footprint will enable
better heat transfer from the
device, especially where there
are internal ground and power
planes.
2. Place the input and output
capacitors close to the device
for optimal transient response
and device behavior.
PD(MAX) = (TJ(max) – TA) / θJA
T J(max) is the maximum junction
temperature of the die and is 125oC.
TA is the ambient temperature. θJA is
the junction-to-ambient thermal
resistance of the package. The SOT23 package has a θJA of approximately
191oC/W and the SC70 package has
a θJA of approximately 330oC/W.
Oct17-06 Rev AC
3. Connect all ground connections
directly to the ground plane. In
case there is no ground plane,
connect to a common ground
point before connecting to
board ground.

Question:
Are the connection details of a fixed version LDO the same as the adjustable version? I went through the datasheet
provided -- it has connection details of only the adjustable version. Do I have to connect resistor R1 AND R2 even
in the fixed version?
Answer:
An LDO with fixed output such as the SPX1587 does not require external voltage divider resistors for they are
internal. Only the Adjustable versions need a divider for setting output voltage. This info is generally within the
Datasheet. The external resistor voltage divider is only used for programming the output voltage of an adjustable
part. For the fixed output part, simply connect the ADJ/GND input (pin 1) to GND for typical configuration. Below
diagram is from the SPX1585 data sheet showing how a basic fixed regulator is configured. Pin 1 is GND, Pin 2 is
Vout and Pin 3 is Vin. Please keep in mind that the package tab is usually connected to Vout and should be isolated
if the tab is connected to your GND plane. Some designers will enlarge the Vout plane to allow for the tab connection
resulting in no need to isolate tab.
Question:
Is there a simple way to figure out heat loss for an LDO?
Answer:
Yes. Try our Excel-based heat calculation spreadsheet ANP2 available online at http://www.sipex.com/files/
ApplicationNotes/ThermalCalculator.xls
For further study, this spreadsheet is mentioned in the following helpful application note: “ANP2:
Considerations for Linear Regulators” http://www.sipex.com/files/ApplicationNotes/LDOThermal.pdf

Device Description
The SP6222 and SP6223 are CMOS LDOs designed to meet a broad range of applications that require
accuracy, speed and ease of use. These LDOs offer extremely low quiescent current which only increases
slightly under load, thus providing advantages in ground current performance over bipolar LDOs. The
LDOs handle an extremely wide load range and guarantee stability with a 1µF ceramic output capacitor.
They have excellent low frequency PSRR, not found in other CMOS LDOs and thus offer exceptional Line
Regulation. High frequency PSRR is 55dB (typical) at 1kHz. Load Regulation is excellent and temperature
stability is comparable to bipolar LDOs. An enable feature is provided on all versions. The SP6222/6223 is
available in fixed and adjustable output voltage versions in industry standard SC70 and SOT23 packages.

Life Test
Life testing is conducted to determine if there are any fundamental reliability related
failure mechanism(s) present in the device.
These failure mechanisms can be divided roughly into four groups:
Process or die related failures, such as oxide-related defects, metalization-related
defects and diffusion-related defects.
2. Assembly-related defects such as chip mount wire bond or package-related
failures.
3. Design related defects.
4. Miscellaneous, undetermined or application- induced failures.
1.
Life Test Results
As part of the Sipex design qualification program, the Engineering group had subjected
211 SP6223 parts for a 1000 hour Reliability life test at 125° C
168 hour Life test
211 parts were sub jected to the life test profile and completed 168 hours without
any part failures.
500 hour Life test
The 211 parts were re-introduced to the second phase of the test, where the parts
successfully completed the 500- hour life test without any failures.
1000 hour Life test
211 parts completed the full1000 hour life/HTOL test successfully, without
showing any significant shift in the process parameters.

FIT Rate Calculations
The FIT (failures in time) rate is the predicted number of failures per billion devicehours. This predicted value is based upon the:
Life Test conditions (time and temperature, device quantity and number of failures)
are summarized under HTOL test table.
2. Activation Energy (Ea) of the potential failure modes.
1.
The weighted Activation Energy, Ea, of observed failure mechanisms of Sipex products
has been determined to be 0.8 eV.
Based on the above criteria, the FIT rates at 25°, 55° and 70°C operation at both 60% and
90% confidence levels for the SP331 family products have been calc ulated and are listed
below.
