120mA 2ch LDO REGULATOR
The R5322N Series are voltage regulator ICs with high output voltage accuracy, low
supply current, low
dropout, and high ripple rejection by CMOS process. 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 and prolong the battery life of each system. The line transient response and load transient response
of
the R5322N 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 is
SOT-23-6W package, and include 2ch LDO regulators each, high density mounting of the ICs on boards is
possible. |
