RS7206
300mA CMOS LDO Linear Regulator with Enable
Page No. : 1/16
General Description
The RS7206 is a 4‐Low (Low‐dropout, Low‐quiescent Current, Low‐noise, Low‐cost) linear regulator with ON/OFF control.
The device operates in the input voltage range from +2.2V to +7.0V and delivers 300mA output current.
The high‐accuracy output voltage is preset at an internally trimmed voltage 1.2V, 1.5V, 1.8V, 2.5V, 2.8V, 3.0V or 3.3V. Other
output voltages can be mask‐optioned from 1.2V to 5.0V with 100mV increment.
The RS7206 consists of a 1.0V reference compare amplifier, a P‐channel pass transistor, and an enable/disable logic circuit.
Other features include short‐circuit protection, and thermal shutdown protection.
The RS7206 is also compatible with low ESR ceramic capacitors which give added output stability. This stability can be
maintained even during load fluctuations due to the excellent transient response of the chip. The RS7206 devices are
available in SOT‐25 and VSON‐6 (2x2) 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.
