OVERSTRESS CAUTION
Stresses beyond those listed may cause permanent damage
to the device. Functional operation of the device at these or
any other conditions beyond those indicated in the
operational section of the specification is not implied.
Exposure to absolute maximum rating conditions for extended
periods may affect reliability.
ESD SENSITIVITY CAUTION
This integrated circuit can be damaged by ESD if you don’t
pay attention to ESD protection. 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 very small parametric changes could cause
the device not to meet its published specifications.
DISCLAIMER
SG Micro Corp reserves the right to make any change in
circuit design, specification or other related things if
necessary without notice at any time.

NOTES:
1. VIN = VOUT (NOMINAL) + 0.5V or 2.5V, whichever is greater.
2. The dropout voltage is defined as VIN - VOUT, when VOUT is 100mV below the value of VOUT for VIN = VOUT + 0.5V.
(Only applicable for VOUT = +2.5V to +5.0V.)
3. VEN = -0.3V to VIN
4. Time needed for VOUT to reach 90% of final value.
5. Maximum output current is affected by PCB layout, size of metal trace, the thermal conduction path between metal layers,
operating temperature and the other environment factor of system.

APPLICATION NOTE
When LDO is used in handheld products, attention must be paid to voltage spikes which could damage SGM2031.
In such applications, voltage spikes will be generated at charger interface and VBUS pin of USB interface when
charger adapters and USB equipments are hot-plugged. Besides this, handheld products will be tested on the
production line without battery. Test engineer will apply power from the connector pin which connects with positive
pole of the battery. When external power supply is turned on suddenly, the voltage spikes will be generated at the
battery connector. The voltage spikes will be very high, and it always exceeds the absolute maximum input voltage
(6.0V) of LDO. In order to get robust design, design engineer needs to clear up this voltage spike. Zener diode is a
cheap and effective solution to eliminate such voltage spike. For example, BZM55B5V6 is a 5.6V small package
Zener diode which can be used to remove voltage spikes in cell phone designs. The schematic is shown below.
