RS7100
Low Power 300mA CMOS LDO
General Description
The RS7100 is a low‐dropout linear regulator that operations in the input voltage range from +2.5V to +9.0V and delivers
300mA output current. The high‐accuracy output voltage is preset at an internally trimmed voltage 2.5V or 3.3V. Other
output voltages can be mask‐optioned from 1.5V to 5.0V with 100mV increment.
The RS7100 consists of a 1.25V bandgap reference, an error amplifier, and a P‐channel pass transistor. Other features
include short‐circuit protection and thermal shutdown protection. The RS7100 devices are available in SOT‐23 and SOT‐89
packages.

Application Circuits
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.
