FEATURES

APPLICATIONS

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 1F 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.

SP6222/6223 50/150mA CMOS Linear Regulators

General Overview

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.

Enable / Shutdown Operation

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.

Input / Output Capacitor

The SP6222/6223 is designed to
operate using very small ceramic
capacitors. The minimum input and
output capacitor value for stable
operation is 1.0F. 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.

Adjustable Regulator

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

the output voltage based on the
following equation:

OUT

= V

REF

*(R1/R2 + 1)

Resistor values are not critical
because the ADJ (adjust) pin has a
high impedance, but for best
performance use resistor values of
470K or less.

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:

D(MAX)

= (T

J(max)

) /

J(max)

is the maximum junction

temperature of the die and is 125

is the ambient temperature.

the junction-to-ambient thermal
resistance of the package. The SOT-
23 package has a

of approximately

191

C/W and the SC70 package has

of approximately 330

C/W.

The actual power dissipation of the
regulator circuit can be determined
by using the simplified equation:

= (V

OUT

) * I

OUT

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.

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.
