RS7213
300mA High Speed, Low Noise LDO with Fast Enable and Fast Discharge Function
Page No. : 1/9
General Description
The RS7213 series is a low‐dropout linear regulator with ON/OFF control that operates in the input voltage range from
+1.8V to +5.5V and delivers 300mA output current.
The fixed output voltage is preset at an internally trimmed voltage 1.8V, 2.5V, or 3.3V. Other options 1.0V, 1.2V, 1.5V, 2.2V,
3.0V and 3.6V are available by special order only.
The RS7213 consists of a 0.87V bandgap reference, an error amplifier, and a P‐channel pass transistor. Other features
include short‐circuit protection, thermal shutdown protection, fast respond and fast discharge functions. The RS7213 series
devices are available in SOT‐25 & SC‐70‐5 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.
