RS7302
600mA Adjustable & Fixed Voltage LDO Linear Regulator with Enable, Fast Discharge & Soft‐Start
General Description
The RS7302 series is a low‐dropout linear regulator with ON/OFF control that operates in the input voltage range from
+2.4V to +7.0V and delivers 600mA output current.
The RS7302 is available fixed output voltage type is preset at an internally trimmed voltage 1.8V, 2.5V, or 3.3V. Other
options 1.0V, 1.2V,1.5V, 2.85V, 3.0V and 3.6V are available by special order only.
The RS7302 series consists of a 0.95V bandgap reference, an error amplifier, and a P‐channel pass transistor. Other
features include soft‐start function, short‐circuit protection and thermal shutdown protection. The RS7302 series devices
are available in SOT‐25, SC‐70‐5 & SOP‐8 packages.

Application Circuits
Soft‐Start Function
This integrated circuit can be damaged by ESD. Orister Corporation 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.
