rp106x series 0.8%accuracy 0.7v output 400 ma ldo regulator no.ea - 180 - 131017 1 outline the rp106x series are low voltage 400ma voltage regulator. these ics had been further improved of low - voltage capability compared with previous low - voltage product. the input voltage is as low as min. 1.0v and the output voltage can be set from 0. 7v. the output voltage accuracy has been improved to 0.8% and due to a built - in transistor with low on - resistance of 0.55 ? (at v out = 1.5v) . each of these ics consists of a voltage reference unit, an error amplifier, a resistor - net for voltage setting, and a current limit circuits for over - current for the destruction prevention by the over - current. the ce pin can switch the regulator to standby mode. in addition to sot - 23- 5 and sc - 88a packages, a 0.69mm square wlcsp -4- p5 package and a 1.2mm square dfn(plp)1212 - 6 are also available. features ?
