450mA, Ultra-Low Noise and High PSRR
Linear Regulator in Ultra-Thin Package
SGM2061
APPLICATION INFORMATION
The SGM2061 is an ultra-low noise and low dropout
LDO and provides 450mA 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 SGM2061 useful in a variety of applications.
The SGM2061 provides the protection function for
output overload, output short-circuit condition and
overheating.
When the EN pin voltage is lower than 0.6V, 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 270Ω (TYP) resistor.
When the EN pin voltage is higher than 1V, the device
is in active state, the input voltage is regulated to the
output voltage and the automatic discharge transistor is
turned off.
The SGM2061 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 0.03μA (TYP).
The EN pin is pulled down by internal 0.03μA (TYP)
current source when the EN pin is floated. This current
source will ensure the SGM2061 in shutdown state and
reduce the power dissipation in system.
Input Capacitor Selection (CIN)
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.
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 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.
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 Capacitor Selection (COUT
)
The output decoupling capacitor should be placed as
close as possible to the OUT pin. 1μF or larger X7R or
X5R ceramic capacitor is selected to get good dynamic
performance. The minimum effective capacitance of
COUT that SGM2061 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.
Additionally, COUT with larger capacitance and lower
ESR will help increase the high frequency PSRR and
improve the load transient response.
Output Current Limit and Short-Circuit
Protection
When overload events happen, the output current is
internally limited to 900mA (TYP). When the OUT pin is
shorted to ground, the short-circuit protection will limit
the output current to 500mA (TYP).
Thermal Shutdown
The SGM2061 can detect the temperature of die. When
the die temperature exceeds the threshold value of
thermal shutdown, the SGM2061 will be in shutdown
state and it will remain in this state until the die
temperature decreases to +140℃.
Enable Control
The EN pin of the SGM2061 is used to enable/disable
its device and to deactivate/activate the output
automatic discharge function.

APPLICATION INFORMATION (continued)
The maximum allowable power dissipation depends on
Power Dissipation (PD)
the thermal resistance of the IC package, the PCB
layout, the rate of surrounding airflow, and the
difference between the junction temperature and
ambient temperature. The maximum power dissipation
can be approximated using the following equation:
Thermal protection limits power dissipation in the
SGM2061. When power dissipation on pass element
(PD = (VIN - VOUT) × IOUT) is too much and the operating
junction temperature exceeds +160℃, the OTP circuit
starts the thermal shutdown function and turns the pass
element off.
PD(MAX) = (TJ(MAX) - TA) / θJA
(1)
Therefore, thermal analysis for the chosen application is
important to guarantee reliable performance over all
conditions. To guarantee reliable operation, the junction
temperature of the SGM2061 must not exceed +125℃.
where TJ(MAX) is the maximum junction temperature, TA
is the ambient temperature, and θJA is the junction
-to-ambient thermal resistance.
