RP154x

RP154x SERIES 300mA SMALL DUAL LDO REGULATOR NO. EA-202-141010 OUTLINE The RP154x Series are CMOS-based voltage regulator ICs that provide high ripple rejection, low dropout voltage, high output voltage accuracy, and low supply current. The RP154x Series consist of a voltage reference unit, an error amplifier, resistors for setting output voltage, a short current limit circuit, and a chip enable circuit. The RP154x Series are available in fixed output voltage options. Besides the low supply current by CMOS, the RP154x Series present a low dropout voltage by built-in low ON resistance Tr. and an extended battery life by a chip enable function. Compared with the existing CMOS-based regulator ICs, the RP154x Series are further improved in ripple rejection, line transient response, and load transient response. All these features allow the RP154x Series to become ideal power sources for hand-held communication equipments. The RP154x Series are available in two types of packages: SOT-23-6 and DFN1216-8 package with 2 LDOs on board that achieves high-density mounting.
