DESCRIPTION
The IXD1201 is a precise positive voltage regulator
with low power consumption, manufactured using
CMOS technology. Laser trimming guarantees ±1%
precision of the output voltage above 2 V.
The IXD1201regulator is able to provide large
currents at a small dropout voltage.
The IXD1201 consists of a current limiter circuit, a
driver transistor, a precision reference voltage, and
an error amplifier. Output voltage is selectable in
0.1V steps between 1.3 V ~ 6.0 V.
Regulator is available in SOT-25, SOT-89, USP-6B,
and TO-92 packages.

PIN CONFIGURATION
*The dissipation pad for the USP -6B
package should be solder-plated in
recommended mounting pattern and
metal masking to enhance mounting
strength and heat release.
If the pad needs to be connected to
other pins, it should be connected to the
V
SS
(No.5) pin.

TYPICAL APPLICATION CIRCUIT
The output capacitor C
L
≥1 μ
should be connected between the output pin (V
OUT
) and the V
SS
F
pin for stable regulator’s operation.
Ceramic capacitors with low ESR are recommended for output voltages above 1.7 V. For
output voltages in the range from 1.3 V to 1.6 V, we recommend tantalum capacitors C
L
≥
2.2 µF. In addition, the input capacitor C
IN
≥1 μ
should be connected between the V
IN
and the
F
V
SS.
Area of stable regulator’s operation vs. load current and C
L
ESR is shown at the graph below.

LAYOUT AND USE CONSIDERATIONS
1. Mount external component as close to the IC as possible and use thick, short connecting traces to reduce
the circuit impedance.
2. The IC may malfunction if absolute maximum ratings are exceeded.
3. If this voltage regulator is used in schematic, where output voltage may exceed input voltage, a Schottky
barrier diode between V
OUT
and V
IN
pins should be installed in parallel to the regulator with anode
connected to V
OUT
, to prevent V
OUT
from exceeding the V
IN
.
4. If power source of this regulator is a high impedance device with impedance of 10
Ωor
more, an input
capacitor C
IN
≥1μ
should be used to prevent oscillations.
F
5. In case of high output current, increasing the input capacitor value can stabilize operations.
6. Oscillations may occur also, if the input capacitor value is not enough to reduce the input impedance and
the output capacitor C
L
is large. In such case, operations can be stabilized by either increasing the input
capacitor or reducing the output capacitor.
7. Please ensure that output current I
OUT
is less than
P
D
/ (V
IN
- V
OUT
),
where P
D
is a rated power dissipation
value of the package shown at ABSOLUTE MAXIMUM RATING table to not exceed it.
