LOW NOISE 150mA LDO REGULATOR
The R1113Z 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, resistors, a current limit circuit, and a chip
enable circuit.
These ICs perform with low dropout voltage and a chip enable function. The line transient response and load transientresponse
of the R1113Z 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 fixed with high accuracy. Since the
package for these ICs is WLCSP-4-P1 (Wafer Level CSP), high density mounting of the ICs on boards is possible. |
