RS7225

1A Adjustable & Fixed Voltage LDO Linear Regulator with Enable, Fast Discharge & Soft-Start

General Description

The RS7225 series is a low-dropout 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 RS7225 is available fixed output voltage type is preset at an internally trimmed voltage 1.8V, 2.5V, or 3.3V. Other options

1.0V, 1.2V, 1.5V, 2.85V, 3.0V and 3.6V are available by special order only.

The RS7225 series consists of a 0.95V bandgap reference, an error amplifier, and a P-channel pass transistor. Other features

include soft-start function, short-circuit protection and thermal shutdown protection. The RS7225 series devices are available

in SOT-223-5, & TO-252-5 packages.

Application Circuits

Soft-Start Function

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.
