RP154x Series
300 mA Ultra-small Dual LDO Regulator
No. EA-202-171005
OUTLINE
The RP154x is a CMOS-based voltage regulator that provides high ripple rejection, low dropout voltage, high
output voltage accuracy, and low supply current. Internally, the RP154x consists 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 is available in fixed output voltage options. Besides the low supply current by CMOS, the RP154x
offers a low dropout voltage by built-in low ON resistance Tr. as well as an extended battery life by a chip
enable function. Compared with the existing CMOS-based regulators, the RP154x is further improved in ripple
rejection, line transient response, and load transient response. All these features allow the RP154x to become
ideal power sources for hand-held communication equipment.
The RP154x is offered in a 6-pin SOT-23-6 package for a single input type and an 8-pin DFN1216-8 package
for a dual input type. Both packages are equipped with two LDOs which can achieve high-density mounting.
