RP153L SERIES
150mA DUAL LDO REGULATOR WITH 2 INPUT PINS
NO. EA-201-111020
OUTLINE
The RP153L 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 current limit circuit, and a chip enable
circuit.
These ICs perform with low dropout voltage due to built-in transistor with low ON resistance, and a chip
enable function prolongs the battery life of each system. The line transient response and load transient
response of the RP153L 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 with high accuracy. Since the package for these ICs are
DFN1216-8, dual LDO regulators are included in each package are high density mounting of the ICs on boards
is possible.
In RP153L, the power supply of each circuit can be individually supplied. The transient response
characteristic of D and E Version is improved.

ABSOLUTE MAXIMUM RATINGS
Electronic and mechanical stress momentarily exceeded absolute maximum ratings may cause the
permanent damages and may degrade the life time and safety for both device and system using the device
in the field. The functional operation at or over these absolute maximum ratings is not assured.
