150mA Dual LDO REGULATOR
The R5325x Series are CMOS-based voltage regulator ICs with high output voltage accuracy,
low supply
current (Typ. 3.0µA), low dropout, and fast transient response. 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
R5325x Series are excellent, thus these ICs are very suitable for the power supply for hand-held communication
equipment.
The supply current at no load of R5325x Series is remarkably reduced compared with R5323x Series. The
mode change signal to reduce the supply current is not necessary.
The output voltage of these ICs is internally fixed with high accuracy (±1.0%). Since the packages for
these ICs
are SOT-23-6 and DFN(PLP)1820-6 package, dual LDO regulators are included in each, high density mounting of the
ICs on boards is possible. |
