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.

APPLICATION INFORMATION
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 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.
Output Capacitor Selection (COUT)
The output decoupling capacitor should be located as
close as possible to the OUT pin. 0.22μF or larger X7R
or X5R ceramic capacitor is selected to get good
dynamic performance. The minimum effective
capacitance of COUT that SGM2034 can remain stable
is 0.1μF. 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
SG Micro Corp
www.sg-micro.com
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 480mA (TYP). When the OUT pin is
shorted to ground, the short-circuit protection will limit
the output current to 100mA (TYP).
Reverse Current Protection
The SGM2034 incorporates reverse current protection
circuit that prevents current flow backwards through the
pass element when the output voltage is greater than
the input voltage. A comparator senses the difference
between the input and output voltages. When the
difference between the output voltage and input voltage
exceeds 800mV (TYP), the gate of the PFET is
switched to VOUT and the PFET is turned off. Otherwise，
the gate voltage of the PFET is unfixed, and the reverse
current may be (VOUT - VIN) / RON, RON = VDROP / IOUT.
