RS7212  
300mA CMOS LDO Linear Regulator with Enable and Fast Discharge Function  
General Description  
The RS7212 is a 4Low (Lowdropout, Lowquiescent Current, Lownoise, Lowcost) 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 highaccuracy 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 maskoptioned from 1.2V to 5.0V with 100mV increment.  
The RS7212 consists of a 1.0V reference compare amplifier, a Pchannel pass transistor, and an enable/disable logic circuit.  
Other features include shortcircuit protection, and thermal shutdown protection.  
The RS7212 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 RS7212 devices are  
available in SOT25 and VSON6 (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.
