RP154x Series

300mA SMALL DUAL LDO REGULATOR

Outline

The RP154x Series are CMOS-based voltage regulator ICs with high output voltage accuracy, low supply current, low dropout, and high ripple rejection. Each of these voltage regulator ICs consists of a voltage reference unit, an error amplifier, resistors for setting output voltage, a short current limit circuit, a chip enable circuit, and so on.

These ICs perform with low dropout voltage due to built-in transistor with low ON resistance. Low supply current and a chip enable function prolongs the battery life of each system. The ripple rejection, line transient response and load transient response of the RP154 Series are excellent, thus these ICs are very suitable for the power supply for hand-held communication equipment.

The output voltage of these ICs is internally fixed. Since the packages for these ICs are SOT-23-6 and DFN1216-8, and dual LDO regulators are included in each package, high density mounting of the ICs on boards is possible.
