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.

FUNCTION
Enable Pin. This pin has an internal pull-down resistor. A logic low
reduces the supply current to less than 1μA. Connect to IN for normal
operation.
Regulator Input. Supply voltage can range from 1.6V to 5.5V. Bypass
with a 1μF capacitor to GND.
Reference-Noise Bypass Pin (fixed voltage version only). Bypass with a
low-leakage 0.01μF ceramic capacitor for reduced noise at the output. The
capacitor is recommended to be placed very close to the pin for high
PSRR.
Feedback Pin (adjustable voltage version only). This is used to set the
output voltage of the device.
The exposed pad should be connected to a large ground plane to
maximize thermal performance.

NOTES:
1. Maximum output current is affected by the PCB layout, size of metal trace, the thermal conduction path between metal layers,
ambient temperature and the other environment factors of system. Attention should be paid to the dropout voltage when VIN <
VOUT + VDROP.
2. The dropout voltage is defined as VIN - VOUT, when VOUT is 100mV below the value of VOUT for VIN = VOUT + 0.5V or 2.5V.
3. Output voltage temperature coefficient is defined as the worst-case voltage change divided by the total temperature range.
4. Time needed for VOUT to reach 90% of final value.

APPLICATION NOTE
When LDO is used in handheld products, attention must be paid to voltage spikes which could damage SGM2036.
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.
