SGM2024
Quad, Low Power, Low Dropout,
200mA, RF-Linear Regulators
GENERAL DESCRIPTION
The SGM2024 is a quad, low-power, low-dropout, CMOS
linear voltage regulator that operates from 2.5V to 5.5V
input and delivers up to 200mA continuous current at
each channel. An ultra low ground current (350μA at 0mA
output current) makes this part attractive for battery
operated power systems.
The SGM2024 also offers low dropout voltage (220mV at
200mA output) to prolong battery life in portable
electronics. Systems requiring a quiet voltage source,
such as RF applications, will benefit from the SGM2024
series’ ultra low output noise (30µVRMS) and high PSRR.
An external noise bypass capacitor connected to the
device’s BP pin can further reduce the noise level.
Other features include a 10nA logic-controlled shutdown
mode, output current limit and thermal shut-down
protection.
SGM2024 is available in Green TQFN-3×3-16L package.
It operates over an ambient temperature range of -40℃
to +85℃.

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 latest 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.
