RS7215
1A Adjustable & Fixed Voltage LDO Linear Regulator with Enable Function & Fast Discharge
General Description
The RS7215 series is a lowâdropout linear regulator with ON/OFF control that operates in the input voltage range from
+2.4V to +7.0V and delivers 1.0A output current.
The RS7215 is available in two types, fixed output voltage type and adjustable output voltage type. The fixed output
voltage type is preset at an internally trimmed voltage 1.8V, 2.5V, or 3.3V. Other options 1.2V, 1.5V, 2.85V, 3.0V and 3.6V
are available by special order only. The output voltage range of the adjustable type is from 1.175V to 5V.
The RS7215 (ADJ type) consists of a 1.175V bandgap reference, an error amplifier, and a Pâchannel pass transistor. Other
features include shortâcircuit protection and thermal shutdown protection.
The RS7215 (Fixed type) consists of a 0.95V bandgap reference, an error amplifier, and a Pâchannel pass transistor. Other
features include shortâcircuit protection and thermal shutdown protection. The RS7215 series devices are available in SOTâ
223â5, TOâ252â5 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.
