| R1115Z Series |
LOW NOISE 150mA LDO Regulator |
|
| The R1115Z Series are CMOS-based voltage regulator ICs with extremely low supply current, low ON-resistance, and high ripple rejection. Each of these ICs consists of a voltage reference unit, an error amplifier, resistor-net for voltage setting, acurrent 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 transient response of the R1115Z 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-P4, therefore high density mounting of the ICs on boards is possible. |
