APPLICATION INFORMATION
The SGM2053 is a low input voltage, ultra-low noise
and low dropout LDO and provides 500mA 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 SGM2053 useful in a
variety of applications. The SGM2053 provides the
protection function for output overload, output
short-circuit condition and overheating.
When the EN pin voltage is lower than 0.3V, the device
is in shutdown state, there is no current flowing from VIN
to VOUT pins. In this state, the automatic discharge
transistor is active to discharge the output voltage
through a 60Ω (TYP) resistor.
When the EN pin voltage is higher than 0.7V, the device
is in active state, the output voltage is regulated to
expected value and the automatic discharge transistor
is turned off.
The SGM2053 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 SGM2053 in shutdown state and
reduce the power dissipation in system.
Input Capacitor Selection (CIN)
Adjustable Regulator
The input decoupling capacitor is necessary to be
connected as close as possible to the VIN pin for
ensuring the device stability. A 2.2μF or greater X7R or
X5R ceramic capacitor is selected to get good dynamic
performance.
For the SGM2053-ADJ, set the output voltage by using
a resistor divider as shown in Figure 4. Capacitance
CFF = 10nF can be added to improve stability and
reduce noise. Choose R2 = 40kΩ to maintain a 20μA
minimum load. Calculate the value for R1 using the
following equation:
When VIN is required to provide large current
instantaneously, a large effective input capacitor is
required. Multiple input capacitors can reduce the
impact from input trace inductance. Adding more input
capacitors is available to restrict the ringing and to keep
it below the device absolute maximum ratings.

The output decoupling capacitor should be located as
close as possible to the VOUT pin. A 4.7μF or greater
X7R or X5R ceramic capacitor is selected to get good
dynamic performance. The minimum effective
capacitance of COUT that SGM2053 can remain stable
is 1μF. 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.

Output Current Limit and Short-Circuit
Protection
When overload events happen, the output current is
internally limited to 980mA (TYP). When the VOUT pin
is shorted to ground, the short-circuit protection will limit
the output current to 560mA (TYP).
Enable Control
The SGM2053 uses the EN pin to enable/ disable its
device and to deactivate/activate the output automatic
discharge function.

OTP circuit starts the thermal shutdown function and
turns the pass element off.
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 VOUT pin
and GND pin.
Therefore, thermal analysis for the chosen application is
important to guarantee reliable performance over all
conditions. To guarantee reliable operation, the junction
