SP6222/6223 50/150mA CMOS Linear Regulators
2006 Sipex Corporation
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 1.0
μ
F. 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
