RP109x SERIES
LOW NOISE 150mA LDO REGULATOR
NO.EA-204-091013
OUTLINE
The RP109x Series are CMOS-based voltage regulator ICs with high output voltage accuracy, extremely low
supply current, low ON-resistance, and high ripple rejection. Each of these ICs consists of a voltage reference
unit, an error amplifier, a resistor-net for voltage setting, a current limit circuit and a chip enable circuit.
These ICs perform with low dropout voltage and a chip enable function which prolong the battery life.
The line transient response and load transient response of the RP109x Series are excellent, thus these ICs are
very suitable for the power supply for hand-held communication equipment. RP109x Series contributes to the
downsizing of the hand-held equipment because it can use the 0.1μF ceramic capacitor.
In addition to SOT-23-5, SC-88A and DFN1010-4 packages, a 0.8mm square ultra compact DFN(PLP)0808-4
package is also available.

∗) The maximum Input Voltage of the ELECTRICAL CHARACTERISTICS is 5.25V. In case of exceeding this
specification, the IC must be operated on condition that the Input Voltage is up to 5.5V and the total operating
time is within 500hrs.
All of units are tested and specified under load conditions such that Tj≈Topt=25°C except for Output Noise,
Ripple Rejection, Output Voltage Temperature Coefficient.
