SGM2030
Low Power, Low Dropout,
RF - Linear Regulators
GENERAL DESCRIPTION
The SGM2030 series low-power, low-dropout, CMOS
linear voltage regulators operate from a 2.5V to 5.5V
input voltage in an ultra small package. They are the
perfect choice for low voltage, low power applications. A
low ground current makes this part attractive for battery
operated power systems. The SGM2030 series also offer
ultra low dropout voltage to prolong battery life in portable
electronics. Systems requiring a quiet voltage source,
such as RF applications, will benefit from the SGM2030
series’ low output noise and high PSRR.
Other features include a 10nA logic-controlled shutdown
mode, foldback current limit and thermal shut-down
protection.
The SGM2030 is available in Green UTDFN-1.2×1.6-4L
package. It operates over an ambient temperature range
of -40°C to +85°C.

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.
SGMICRO reserves the right to make any change in circuit
design, specification or other related things if necessary without
notice at any time. Please contact SGMICRO sales office to get
the last datasheet.
NOTE:
Stresses beyond those listed under “Absolute Maximum
Ratings” may cause permanent damage to the device. These
are stress ratings only, and functional operation of the device
at these or any other conditions beyond those indicated in the
operational sections of the specifications is not implied.
Exposure to absolute maximum rating conditions for extended
periods may affect device reliability.
