LOW NOISE Dual 300mA LDO
The RP150K Series are CMOS-based dual 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
RP150K 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(1%).
Since the packages for these ICs
are DFN(PLP)2020-8 package,
dual LDO regulators are included in each packages, high density mounting of the ICs
on boards is possible. |
