DESCRIPTION
The RS3003 series is a set of low power high voltage
regulators implemented in CMOS technology. It can
operate from 6.3V to 36V. which can provide 150mA
output current. The device allows input voltage as high
as 36V.
The RS3003 series is available in several fixed output
voltages. CMOS technology ensures low dropout
voltage and low quiescent current.
The RS3003 is available in Green SOT23-3 and
SOT89-3L packages. It operates over an ambient
temperature range of -40° to +85°

Stresses above these ratings may cause permanent damage. Exposure to
absolute maximum conditions for extended periods may degrade device
reliability. These are stress ratings only, and functional operation of the
device at these or any other conditions beyond those specified is not
implied.
ESD SENSITIVITY CAUTION
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.
