RP130x Series Low Noise 150 mA LDO Regulator No. EA-173-181227 OUTLINE The RP130x is a voltage regulator IC with high ripple rejection, low dropout voltage, high output voltage accuracy and extremely low supply current. The IC consists of a voltage reference unit, an error amplifier, a resistor-net for voltage setting, a short current limit circuit and a chip enable circuit. This IC has an excellent low supply current performed by CMOS process, moreover they perform with low dropout voltage due to built-in low on-resistance. A chip enable function prolongs the battery life. The input transient response, the load transient response and the ripple rejection have been improved in the RP130x compared with the conventional products. Besides achieving low supply current (Typ.38 A). The range of the operation voltage is capable from 1.7 V to 6.5 V and the range of the output voltage is capable from 1.2 V to 5.3 V for this product, which is wider range as our conventional product R1114x. The output voltage of this IC is fixed with high accuracy. Since the packages for this IC are DFN(PLP)1010-4, SOT-23-5 and SC-82AB, therefore high density mounting of the IC on board is possible.

A: active low, without auto-discharge function at off state. B: active high, without auto-discharge function at off state. D: active high, with auto-discharge function at off state. (1) Auto-discharge function quickly lowers the output voltage to 0 V by releasing the electrical charge in the external capacitor when the chip enable signal is switched from the active mode to the standby mode. 2
