SGM2036-0.75
APPLICATION INFORMATION
The SGM2036-0.75 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 SGM2036-0.75
useful in a variety of applications. The SGM2036-0.75
provides the protection function for output overload,
output short -circuit condition and overheating.
automatic 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 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 SGM2036-0.75 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 0.04μA (TYP).
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 SGM2036-0.75 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. 1μF or greater X7R or
X5R ceramic capacitor is selected to get good dynamic
performance.
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).
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.
Thermal Shutdown
The SGM2036-0.75 can detect the temperature of die.
When the die temperature exceeds the threshold value
of thermal shutdown, the SGM2036-0.75 will be in
shutdown state and it will remain in this state until the
die temperature decreases to +125℃.
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 SGM2036-0.75 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.
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.
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.
+
Enable Control
The SGM2036-0.75 uses the EN pin to enable/disable
its device and to deactivate/activate the output
