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
the output voltage based on the
following equation:
VOUT = VREF *(R1/R2 + 1)
Resistor values are not critical
because the ADJ (adjust) pin has a
high impedance, but for best
www.DpaetarSfhoeremt4aUn.ccoem use resistor values of
470KΩ or less.
The actual power dissipation of the
regulator circuit can be determined
by using the simplified equation:
PD = (VIN – VOUT) * IOUT
To prevent the device from entering
thermal shutdown, maximum power
dissipation cannot be exceeded.
Layout Considerations
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:
PD(MAX) = (TJ(max) – TA) / θJA
TJ(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 SOT-
23 package has a θJAof approximately
191oC/W and the SC70 package has
a θJA of approximately 330oC/W.
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.
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.
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.
