regulator which is designed using CMOS technology. It
provides 250mA output current capability. The
operating input voltage range is from 1.8V to 5.5V and
output voltage range is from 1.2V to 5.0V.
● Operating Input Voltage Range: 1.8V to 5.5V
● Fixed Output Voltage Range: 1.2V to 5.0V
● Adjustable Output Voltage Range: 1.2V to 5.0V
● Output Current Limit: 500mA (TYP)
● Ultra-Low Quiescent Current: 13.5μA (TYP)
● Shutdown Current: 0.1μA (TYP)
● High PSRR: 94dB (TYP) at 1kHz
● Low Dropout Voltage:
Other features include logic-controlled shutdown mode,
short-circuit current limit and thermal shutdown
protection. The SGM2033 has automatic discharge
function to quickly discharge VOUT in the disabled status.
175mV (TYP) at 250mA when VOUT = 1.8V
(SOT-23-5)
145mV (TYP) at 250mA when VOUT = 1.8V
(UTDFN-1×1-4AL)
The SGM2033 is suitable for application which needs
low noise and fast transient response power supply,
such as power supply of camera module in smart
phone, etc.
● Output Short-Circuit Protection
● Thermal Shutdown Protection
● Fast Load Transient Response
● Stable with 1μF Small Case Size Ceramic
Capacitors
The SGM2033 is available in Green SOT-23-5 and
UTDFN-1×1-4AL packages. It operates over an

OVERSTRESS CAUTION
ABSOLUTE MAXIMUM RATINGS
Stresses beyond those listed in Absolute Maximum Ratings
may cause permanent damage to the device. Exposure to
absolute maximum rating conditions for extended periods
may affect reliability. Functional operation of the device at any
conditions beyond those indicated in the Recommended
Operating Conditions section is not implied.

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.

Enable Pin. Drive EN high to turn on the regulator. Drive EN low to turn off
the regulator. The EN pin has an internal 0.2μA pull-down current source
which ensures that the device is turned off when the EN pin is floated. This

Regulated Output Pin. It is recommended to use an output capacitor with
effective capacitance in the range of 0.5μF to 10μF. The capacitor should be
located very close to this pin.

250mA, Ultra-Low Noise and High PSRR
LDO Regulators for RF and Analog Circuits
SGM2033
APPLICATION INFORMATION
The SGM2033 is a low input voltage, ultra-low noise
and low dropout LDO and provides 250mA 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 SGM2033 useful in a
variety of applications. The SGM2033 provides the
protection function for output overload, output short
-circuit condition and overheating.
discharge function.
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 220Ω (TYP) resistor.
When the EN pin voltage is higher than 1.5V, the device
is in active state, the input voltage is regulated to the
output voltage and the automatic discharge transistor is
turned off.
The SGM2033 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 0.1μA (TYP).
The EN pin is pulled down by internal 0.2μA (TYP)
current source when the EN pin is floated. This current
source will ensure the SGM2033 in shutdown state and
reduce the power dissipation in system.
Input Capacitor Selection (CIN)
The input decoupling capacitor is necessary to be
connected as close as possible to the IN pin for
ensuring the device stability. 0.1μF or greater X7R or
X5R ceramic capacitor is selected to get good dynamic
performance.
Adjustable Regulator
The output voltage of the SGM2033 can be adjusted
from 1.2V to 5.0V. The ADJ pin will be connected with
two external resistors as shown in Figure 4, the output
voltage is determined by the following equation:
When VIN is required to provide large current
instantaneously, a large effective input capacitor is
required. Multiple input capacitors can limit the input
tracking inductance. Adding more input capacitors is
available to restrict the ringing and to keep it below the
device absolute maximum ratings.
R
VOUT = VFB × 1+
(1)

R2
where:
VOUT is output voltage and VFB is the internal voltage
reference, VFB = 1.2V.
One parallel capacitor (CFF ≥ 100pF) with R1 can be
used to improve the feedback loop stability and PSRR,
increase the transient response and reduce the output
noise. Use R2 ≤ 100kΩ to maintain a 12μA minimum
load.
Output Capacitor Selection (COUT
)
The output decoupling capacitor should be located as
close as possible to the OUT pin. 1μF or greater X7R or
X5R ceramic capacitor is selected to get good dynamic
performance. The minimum effective capacitance of
COUT that SGM2033 can remain stable is 0.5μF. For
ceramic capacitor, temperature, DC bias and package
size will change the effective capacitance, so enough
margin of COUT must be considered in design. Larger
capacitance and lower ESR COUT will help improve the
load transient response and increase the high
frequency PSRR.

conditions. To guarantee reliable operation, the junction
temperature of the SGM2033 must not exceed 125℃.
Output Current Limit and Short-Circuit
Protection
When overload events happen, the output current is
internally limited to 500mA (TYP). When the OUT pin is
shorted to ground, the short-circuit protection will limit
the output current to 220mA (TYP).
In order to calculate the maximum power that the
device can dissipate, the following formula is used:
PD(MAX) = (125℃ - TA) / θJA
(2)
where TA is the ambient temperature, and θJA is the
junction-to-ambient thermal resistance.
Thermal Shutdown
The SGM2033 can detect the temperature of die. When
the die temperature exceeds the threshold value of
thermal shutdown, the SGM2033 will be in shutdown
state and it will remain in this state until the die
temperature decreases to +145℃.
Negatively Biased Output
When the output is negative voltage, the chip may not
start up due to parasitic effects. Ensure that the output
is greater than -0.3V under all conditions. If excessive
negatively biased output is expected in the application,
a Schottky diode can be added between the OUT pin
and GND pin.
Power Dissipation (PD)
Thermal protection limits power dissipation in the
SGM2033. When power dissipation on pass element
(PD = (VIN - VOUT) × IOUT) is too much that raise the
operation junction temperature exceeds +165℃, the
OTP circuit starts the thermal shutdown function and
turns the pass element off.
Reverse Current
The pass transistor has an inherent body diode which
will be forward biased in the case when VOUT > (VIN
0.3V). If extended reverse voltage operation is
anticipated, external limiting might be appropriate.
+
Therefore, thermal analysis for the chosen application
is important to guarantee reliable performance over all
