range is from 1.8V to 5.5V. The fixed output voltage
range is from 0.8V to 4.2V and adjustable output
voltage range is from 0.8V to 5.0V.
● Operating Input Voltage Range: 1.8V to 5.5V
● Fixed Outputs of 0.8V, 0.9V, 1.0V, 1.05V, 1.1V, 1.2V,
1.8V, 2.5V, 2.8V, 3.0V, 3.3V and 4.2V
● Adjustable Output from 0.8V to 5.0V
● Quiescent Current: 55μA (TYP)
● Low Dropout Voltage:
88mV (TYP) at 1A, VOUT = 3.3V
● EN Pull-Down Current: 120nA (TYP)
Other features include logic-controlled shutdown mode,
short-circuit current limit and thermal shutdown
protection. The SGM2039A has automatic discharge
function to quickly discharge VOUT in the disabled status.
● Current Limiting and Thermal Protection
● Excellent Load and Line Transient Responses
● Stable with Small Case Size Ceramic Capacitors
● SGM2039A: With Output Automatic Discharge

● -40℃ to +125℃ Operating Temperature Range
● Available in a Green XTDFN-1.6×1.2-8L Package
The SGM2039 is suitable for various applications which
need low noise and fast transient response power
supply, such as power supply of camera module in
smart phones. Fixed or adjustable output voltage
versions are provided.
APPLICATIONS
The SGM2039 is available in a Green XTDFN-1.6×1.2-8L
package. It operates over an operating temperature

ESD SENSITIVITY CAUTION
This integrated circuit can be damaged if ESD protections are
not considered carefully. SGMICRO recommends that all
integrated circuits be handled with appropriate precautions.
Failureto observe proper handlingand installation procedures
can cause damage. ESD damage can range from subtle
performance degradation tocomplete device failure. Precision
integrated circuits may be more susceptible to damage
because even small parametric changes could cause the
device not to meet the published specifications.

SGM2039
APPLICATION INFORMATION
The SGM2039 is a low noise, fast transient response
high performance LDO and provides 1A output current.
These features make the device a reliable solution to
solve many challenging problems in the generation of
clean and accurate power supply. The high
performance also makes the SGM2039 useful in a
variety of applications. The SGM2039 provides
protection functions for output overload, output
short-circuit condition and overheating.

Figure 6. Adjustable Output Voltage Application
The SGM2039 provides an EN pin as an external chip
enable control to enable/disable the device. When the
regulator is in shutdown state, the shutdown current
consumes as low as 0.15μA (TYP).
Enable Operation
The EN pin of the SGM2039 is used to enable/disable
the device and to deactivate/activate the output
automatic discharge function (SGM2039A only).
Input Capacitor Selection (CIN)
When the EN pin voltage is lower than 0.4V, the device
is in shutdown state. There is no current flowing from IN
to OUT pins. In this state, the automatic discharge
transistor is active to discharge the output voltage
through a 38Ω (TYP) resistor.
The input decoupling capacitor should be placed as
close as possible to the IN pin for ensuring the device
stability. 1μF or larger X7R or X5R ceramic capacitor is
selected to get good dynamic performance.
When the EN pin voltage is higher than 1.0V, the device
is in active state. The output voltage is regulated to the
expected value and the automatic discharge transistor
is turned off.
Output Capacitor Selection (COUT
)
The output capacitor should be placed as close as
possible to the OUT pin. 2.2μF or larger X7R or X5R
ceramic capacitor is selected to get good dynamic
performance. The minimum effective capacitance of COUT
that SGM2039 can remain stable is 1.5μF. For ceramic
capacitor, temperature, DC bias and package size will
change the effective capacitance, so enough margin of
COUT must be considered in design. Additionally, COUT
with larger capacitance and lower ESR will help
increase the high frequency PSRR and improve the
load transient response.
The EN pin is pulled down by an internal 120nA (TYP)
current source when the EN pin is floated. This current
source will ensure the SGM2039 in shutdown state and
reduce the power dissipation in system.
Reverse Current Protection
The PMOS power transistor has an inherent body
diode. This body diode will be forward biased when
VOUT > VIN. When VOUT > VIN, the reverse current
flowing from the OUT pin to the IN pin will damage the
SGM2039. If VOUT > VIN event would happen in system,
one external diode will be added between OUT pin and
IN pin in circuit design to protect the SGM2039.
Adjustable Regulator
The output voltage of the SGM2039A/B-ADJ can be
adjusted from 0.8V to 5.0V. The ADJ pin will be
connected to two external resistors as shown in Figure 6,
the output voltage is determined by the following
equation:
Output Current Limit and Short-Circuit
Protection
When overload events happen, the output current is
internally limited to 1.45A (TYP). When the OUT pin is
shorted to ground, the short-circuit protection will limit
the output current to 1.45A (TYP).
R

V
OUT = VADJ × 1+
(1)
R2
where:
VOUT is output voltage and VREF is the adjustable
reference voltage, VADJ = 0.8V.
Thermal Shutdown
One parallel capacitor (CFF) with R1 can be used to
improve the feedback loop stability and PSRR,
increase the transient response and reduce the output
noise. R1 and R2 can be calculated for any output
voltage range using Equation 1. Choose R2 ≤ 16kΩ to
maintain a 50μA minimum load.
The SGM2039 can detect the temperature of die. When
the die temperature exceeds the threshold value of
thermal shutdown, the SGM2039 will be in shutdown
state and it will remain in this state until the die
temperature decreases to +145℃.
