RS7103

Low Power 300mA CMOS LDO with Enable

General Description

The RS7103 is a low‐dropout linear regulator that operates in the input voltage range from +2.5V to +9.0V and delivers

300mA output current.

The high‐accuracy output voltage is preset at an internally trimmed voltage 2.5V or 3.3V. Other output voltages can be

mask‐optioned from 1.5V to 5.0V with 100mV increment.

The RS7103 consists of a 1.25V reference, an error amplifier, a P‐channel pass transistor, and an enable/disable logic

circuit. Other features include short‐circuit protection, soft start function, and thermal shutdown protection. The RS7103

device is available in SOT‐25 package.
