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.

SGM2035C
500mA, Ultra Low Dropout,
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
makes the SGM2035C useful in a variety of
applications. The SGM2035C provides protection
functions for output overload, output short-circuit
condition and overheating.
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. 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.
Enable Control
The SGM2035C uses the EN pin to enable/disable its
device.
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.
SG Micro Corp
www.sg-micro.com
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.
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℃.
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.
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℃.
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.
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.
