Preliminary Datasheet
SGM2202
150mA, High PSRR, High Voltage Regulators
GENERAL DESCRIPTION
The SGM2202 series is a set of low power high voltage
regulators implemented in CMOS technology which can
provide 150mA output current. The device allows input
voltage as high as 36V. The SGM2202 series is
available in adjustable and several fixed output
voltages. CMOS technology ensures low dropout
voltage and low quiescent current.
Although designed primarily as fixed voltage regulators,
the device can be used with external components to
obtain variable output voltages.
The SGM2202 series is available in Green SOT-23-5
and SOT-23-6 packages. It operates over an ambient
temperature range of -40℃ to +85℃.

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.
RECOMMENDED OPERATING CONDITIONS
Input Voltage Range ........................................... 2.7V to 36V
Operating Temperature Range ...................... -40℃ to +85℃
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. 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 V
