dropout voltage linear regulator. It is capable of
supplying 300mA output current with typical dropout
voltage of only 165mV. The operating input voltage
range is from 1.6V to 5.5V. The output voltage range is
from 0.8V to 5.0V in fixed output version. For
adjustable output version, the output voltage can be
adjusted from 0.8V to 5.0V by using external resistors.
Other features include logic-controlled shutdown mode,
short-circuit current
limit
and

OVERSTRESS CAUTION
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.
Failure to observe proper handling and installation procedures
can cause damage. ESD damage can range from subtle
performance degradation to complete 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.
DISCLAIMER
SG Micro Corp reserves the right to make any change in
circuit design, or specifications without prior notice.

Regulator Output Pin. It is recommended to use a ceramic capacitor with
effective capacitance in the range of 0.5μF to 10μF to get good power

Enable Pin. Drive EN high to turn on the regulator. Drive EN low to turn
off the regulator. This pin must be pulled high by an external resistor
connected to IN pin if EN pin is not used.
Input Voltage Supply Pin. It is recommended to use a 1μF or larger
ceramic capacitor from IN pin to ground. This ceramic capacitor should
be placed as close as possible to IN pin.
Reference-Noise Bypass Pin (fixed voltage version only). Bypass with an
external capacitor CBP can reduce output noise to very low level. The
capacitor is recommended to be placed very close to the pin for high
PSRR.
Feedback Voltage Input Pin (adjustable voltage version only). Connect
this pin to the external resistor divider to adjust the output voltage. Place
the resistors as close as possible to this pin.
Exposed Pad. Connect it to GND internally. Connect it to a large ground
plane to maximize thermal performance; this pad is not an electrical
connection point.

SGM2036
300mA, Low Power
and Low Dropout RF Linear Regulator
APPLICATION INFORMATION
The SGM2036 is a low input voltage, ultra-low noise
and low dropout LDO and provides 300mA 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 SGM2036 useful in a
variety of applications. The SGM2036 provides the
protection function for output overload, output short
-circuit condition and overheating.
The SGM2036 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 0.01μA (TYP).
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. 1μF or greater X7R or
X5R ceramic capacitor is selected to get good dynamic
performance.
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.
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 SGM2036 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.
Enable Control
The SGM2036 uses the EN pin to enable/disable its
device and to deactivate/activate the output automatic
discharge function.
SG Micro Corp
www.sg-micro.com
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 50Ω (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 EN pin is pulled down by internal 0.8μA (TYP)
current source when the EN pin is floated. This current
source will ensure the SGM2036 in shutdown state and
reduce the power dissipation in system.
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.
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.
Output Current Limit and Short-Circuit
Protection
When overload events happen, the output current is
internally limited to 560mA (TYP). When the OUT pin is
shorted to ground, the short-circuit protection will limit
the output current to 200mA (TYP).
Thermal Shutdown
The SGM2036 can detect the temperature of die. When
the die temperature exceeds the threshold value of
thermal shutdown, the SGM2036 will be in shutdown
state and it will remain in this state until the die
temperature decreases to +140℃.
