ESD Susceptibility
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 tocomplete 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.

SGM2217
1.5A, Low Dropout Positive Regulator
APPLICATION INFORMATION
The SGM2217 is a low noise, high current and low
dropout LDO and provides 1.5A 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 SGM2217 useful in a variety of applications.
The SGM2217 provides protection functions for output
overload, output short-circuit condition and overheating.

Output Current Limit and Short-Circuit
Protection
When overload events happen, the output current is
internally limited to 3A (TYP). When the OUT pin is
shorted to ground, the short-circuit protection will limit
the output current.
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. 10μF 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.
Thermal Shutdown
The SGM2217 can detect the temperature of die. When
the die temperature exceeds the threshold value of
thermal shutdown, the SGM2217 will be in shutdown
state and it will remain in this state until the die
temperature decreases to +140℃.
Output Capacitor Selection (COUT
)
Power Dissipation (PD)
The output decoupling capacitor should be located as
close as possible to the OUT pin. 10μF or larger X7R or
X5R ceramic capacitor is selected to get good dynamic
performance. The minimum effective capacitance of
COUT that SGM2217 can remain stable is 2.3μF. 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.
Thermal protection limits power dissipation in the
SGM2217. 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.
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 SGM2217 must not exceed +125℃.
The maximum allowable power dissipation depends on
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:
Adjustable Regulator
The output voltage of the SGM2217-ADJ can be
adjusted from 1.25V to 26V. The ADJ pin will be
connected to two external resistors as shown in Figure 4.
The output voltage is determined by the following
equation:
PD(MAX) = (TJ(MAX) - TA) / θJA
(3)
R
2
VOUT =1.25V× 1+
(1)
where TJ(MAX) is the maximum junction temperature, TA
is the ambient temperature, and θJA is the junction
-to-ambient thermal resistance.
R1
One parallel capacitor (CFF) with R2 can be used to
improve the feedback loop stability and PSRR,
increase the transient response and reduce the output
noise.
