RP130x-Y Series Low Noise 150mA LDO Regulator for Industrial Applications NO.EA-336-200129 OUTLINE The RP130x is a CMOS-based positive voltage regulator IC with high ripple rejection, low dropout voltage, high output voltage accuracy and extremely low supply current. The RP130x consists of a voltage reference unit, an error amplifier, a resistor network for voltage setting, a short current limit circuit, and a chip enable circuit. The RP130x has low supply current characteristics in the CMOS process. In addition, the RP130x can supply a low dropout voltage, which becomes the smallest difference between the input voltage and output voltage by having a low on-resistance and also can achieve the battery s long life by a chip enable function. When compared with the conventional products of high-speed type, the RP130x achieves low consumption current of 38A (Typ.) while improving the input transient response, the load transient response, and the ripple rejection. The RP130x supports two package types: DFN(PLP)1010-4 and SOT-23-5. By the adoption of the ultra- compact DFN(PLP)1010-4, the RP130x can achieve a higher density mounting than ever. This is a high-reliability semiconductor device for industrial applications (-Y) that has passed both the screening at high temperature and the reliability test with extended hours.
