CAT6220
300 mA Adjustable Voltage
LDO Regulator
Description
The CAT6220 is a 300 mA CMOS low dropout regulator whose
output voltage is user adjustable that provides fast response time
during load current and line voltage changes.
http://onsemi.com
With 1 mA of shutdown current, an internal no−load operating
current of only 10 mA, and full−load operating current of 40 mA, the
CAT6220 is ideal for battery−operated devices with supply voltages
from 2.3 V to 6.5 V.
The CAT6220 offers 1% initial accuracy and low dropout voltage,
270 mV typical at 300 mA. Stable operation is provided with a small
value ceramic capacitor, reducing required board space and
component cost.

Pin Function
A small 1 mF ceramic bypass capacitor is required
between the VOUT pin and ground. For better transient
response, its value can be increased to 2.2 mF. This capacitor
should be located near the device.
VIN is the supply pin for the LDO. A small 1 mF ceramic
bypass capacitor is required between the V pin and ground
IN
near the device. When using longer connections to the power
supply, C value can be increased without limit. The
operating input voltage range is from 2.3 V to 6.5 V.
GND is the ground reference for the LDO. This pin must be
connected to the system ground line or the ground plane of
the PCB.
The backside center pad of the TDFN package is
internally connected to the GND pin. Any PCB connection
to this pad must be either floating or at GND potential.
IN
EN is the enable control logic (active high) for the regulator
output. Enable is a high impedance input and must not be left
unconnected. Floating EN will result in unpredictable action
at VOUT.
ADJ is the LDO’s voltage control input. This pin is
connected to the center of the resistor voltage divider R1,
R2. A 10 pF capacitor connected in parallel with R1 will
improve the transient load regulation for VOUT ≤ 2 V.
VOUT is the LDO regulator’s output. Output voltage is set
by two external resistors arranged as a voltage divider
between VOUT and Ground. The center point of the divider
is connected to ADJ as shown in Figure 2. The minimum
recommended current through resistors is 5 mA. The ratio of
the resistors is set by the formula:
Thermal and Short Circuit Protection
CAT6220 is equipped with thermal protection and
over−current limiting circuitry.

+ 1.24 V ǒ1 ) Ǔ
VOUT
In the event of a short circuit CAT6220 will limit its output
current to approximately 400 mA. If the short circuit persists
CAT6220’s internal temperature will rise and if the chip’s
temperature reaches 140°C CAT6220 will shut off all
current to the load which protects the system and allows the
LDO to cool down. When the LDO’s internal temperature
drops below 130°C the LDO automatically turns ON again.
If the short circuit is still present another thermal cycle will
ensue. This will continue until either the short circuit is
removed or the Enable pin is taken LOW.

For the TSOT23−5 package, a continuous 300 mA output
current may turn−on the thermal protection. If this happens
the LDO will respond by shutting off power to the load and
thermal cycling will begin.
