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.

SGM2032
Low Power, Low Dropout,
RF Linear Regulators
APPLICATION INFORMATION
The SGM2032 is a low power and low dropout LDO and
provides 300mA 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
SGM2032 useful in a variety of applications. The
SGM2032 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 SGM2032 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
SG Micro Corp
www.sg-micro.com
load transient response and increase the high
frequency PSRR.
Enable Control
The SGM2032 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.
Output Current Limit and Short-Circuit
Protection
When overload events happen, the output current is
internally limited to 500mA (TYP). When the OUT pin is
shorted to ground, the short-circuit protection will limit
the output current.
Thermal Shutdown
The SGM2032 can detect the temperature of die. When
the die temperature exceeds the threshold value of
thermal shutdown, the SGM2032 will be in shutdown
state and it will remain in this state until the die
temperature decreases to +135℃.
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.
