GENERAL DESCRIPTION
The SGM2061 is a low noise, high PSRR and low
dropout voltage linear regulator. It is capable of
supplying 450mA output current with typical dropout
voltage of only 70m V. The operating input voltage
range is from 1.9V to 5.5V. The fixed output voltages
are 1.8V, 2.5V, 2.8V, 3.0V, 3.3V and 5.0V.
Other features include logic-controlled shutdown mode,
short-circuit current limit and thermal shutdown
protection. The SGM2061 has automatic discharge
function to quickly discharge V
OUT
in the disabled status.
The SGM2061is suitable for applications which need
low noise and fast transient response power supply,
such as power supply of camera module in smart
phone, etc.
The SGM2061 is available in an ultra-thin Green
WLCSP-0.64×0.64-4B-A package. It operates over an
operating temperature range of -40℃ to +125℃.

OVERSTRESS CAUTION
Stresses beyond those listed in Absolute Maximum Ratings
may cause permanent damage to the device. Exposure
to
absolute maximum rating conditions for extended periods
may affect reliability. Functional operation of the device at any
conditions beyond those indicated in the Recommended
Operating Conditions section
is not implied.
ESD SENSITIVITY CAUTION
This integrated circuit can be damaged if ESD protections are
not considered carefully. 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 even small parametric changes could cause the
device not to meet the published specifications.
DISCLAIMER
SG Micro Corp reserves the right to make any change in
circuit
design, or specifications
without prior notice.
