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.

Note 1. The maximum allowable power dissipation at any TA (ambient temperature) is PD (MAX) = (TJ (MAX)– TA) /
θJA. Exceeding the maximum allowable power dissipation will result in excessive die temperature, and
the regulator will go into thermal shutdown. The θJA of the SP6222/23 (SC-70-5) is 330°C/W mounted
on a PC board with minimum copper area (see “Thermal Considerations” section for further details).
Note 2. Minimum VIN must meet 2 conditions: VIN >1.6V and VIN > {VOUT + DOV}
Note 3. Dropout Voltage DOV is defined as the input to output differential at which the output voltage drops
2% below its nominal value measured at 1V differential. The DOV specification is not applicable to
output voltages less than 2.7V.

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.
Date: 6/15/06 Rev AB
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

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.
Date: 6/15/06 Rev AB
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.
