RS7103
Low Power 300mA CMOS LDO with Enable
Page No. : 1/10
General Description
The RS7103 is a lowâdropout linear regulator that operates in the input voltage range from +2.5V to +9.0V and delivers
300mA output current.
The highâaccuracy output voltage is preset at an internally trimmed voltage 2.5V or 3.3V. Other output voltages can be
maskâoptioned from 1.5V to 5.0V with 100mV increment.
The RS7103 consists of a 1.25V reference, an error amplifier, a Pâchannel pass transistor, and an enable/disable logic
circuit. Other features include shortâcircuit protection, soft start function, and thermal shutdown protection. The RS7103
device is available in SOTâ25 package.
