ESD Susceptibility  
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.

500mA, Ultra Low Dropout,  
SGM2035C  
Low Power, RF Linear Regulator  
APPLICATION INFORMATION  
The SGM2035C is a low power 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  
Output Current Limit and Short-Circuit  
Protection  
When overload events happen, the output current is  
internally limited to 510mA (MIN). When the OUT pin is  
shorted to ground, the short-circuit protection will limit  
the output current.  
makes the SGM2035C useful in  
a
variety of  
applications. The SGM2035C provides protection  
functions for output overload, output short-circuit  
condition and overheating.  
Thermal Shutdown  
The SGM2035C can detect the temperature of die.  
When the die temperature exceeds the threshold value  
of thermal shutdown, the SGM2035C will be in  
shutdown state and it will remain in this state until the  
die temperature decreases to +135.  
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.  
Power Dissipation (PD)  
Thermal protection limits power dissipation in the  
SGM2035C. When power dissipation on pass element  
(PD = (VIN - VOUT) × IOUT) is too much and the operating  
junction temperature exceeds +150, the OTP circuit  
starts the thermal shutdown function and turns the pass  
element off.  
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.  
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 SGM2035C must not exceed +125.  
Output Capacitor Selection (COUT  
)
The output decoupling capacitor should be located 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 SGM2035C 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.  
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:  
PD(MAX) = (TJ(MAX) - TA) / θJA  
(3)  
where TJ(MAX) is the maximum junction temperature, TA  
is the ambient temperature, and θJA is the junction  
-to-ambient thermal resistance.  
Enable Control  
The SGM2035C uses the EN pin to enable/disable its  
device.  
Layout Guidelines  
To get good PSRR, low output noise and high transient  
response performance, the input and output bypass  
capacitors must be placed as close as possible to the  
IN pin and OUT pin separately. VIN and VOUT had better  
use separate ground planes and these ground planes  
are single point connected to the GND pin.  
When the EN pin voltage is lower than 0.3V, the device  
is in shutdown state. When the EN pin voltage is higher  
than 1.5V, the device is in active state. The output  
voltage is regulated to expected value.
