| R5510H Series |
LDO Regulator with Reset |
|
| The R5510Hxxxx series are voltage regulator(VR) ICs equipped with a voltage detector(VDET) by CMOS process. VR function of the R5510Hxxxx has features of high ripple rejection, low dropout voltage, high output voltage accuracy, and ultra-low supply current. Each of these ICs consists of a voltage reference unit, an error amplifier, resistors for setting output voltage, a current limit circuit, and a voltage detector. Each of the R5510HxxxA/B/C types includes also a chip enable circuit. The output of built-in voltage detector is Nch open drain type. The R5510HxxxD type has a pin for connecting external capacitor to set a certain reset delay time instead of chip enable control pin. VR Output Voltage of the R5510HxxxE/F/G types is adjustable with external resistors.The regulator output voltage except R5510HxxxE/F/G types and the detector threshold voltage are fixed in the IC. Low supply current by the merit of CMOS process and built-in transistors with low ON-resistance make low dropout voltage. These regulators in the R5510Hxxxx series are remarkable improvement on the current regulators in terms of ripple rejection, input transient response, and load transient response. Furthermore, the R5510HxxxA to G series can supervise input voltage by the built-in detector. R5510HxxxH/J/K types can supervise VSEN pin voltage by the built-in detector. Thus, the R5510Hxxxx series are suitable for power supply for CD-drives, DVD-drives, and so forth. Since the package for these ICs is the SOT-89-5 package, high density mounting of the ICs on boards is possible. |
