Technical content

NO. EA-117-0506 OUTLINE The R1100D Series are CMOS-based voltage regulator ICs with high accuracy output voltage and ultra-low supply current developed. Each of th ese ICs consists of a driver transistor, a voltage reference unit, an error amplifier, resistors for setting output voltage and a current limit circuit. The output voltage of these ICs is fixed with high accuracy. Even if V OUT is shorted to the GND, the included current limit circuit protects the ICs from the destruction. Since the package for these ICs is SON1408-3, high density mounting of the ICs on boards is possible.

FEATURES

±24mV(VOUT <1.2V)

  • Built-in Current Limit Circuit

APPLICATIONS

  • Power source for battery-powered equipment.
  • Power source for cameras, VCRs, camcorders, hand-held audio instruments and hand-held communication equipment.
  • Precision voltage references.

The output voltage, the active type, and the packing type for the ICs can be selectied at the user’s request. The selection can be made with designating the part number as shown below: R1100xxx 1C-xx ←Part Number a b c d e Code Contents a Designation of Package Type D: SON1408-3 b Setting Output Voltage (VOUT): Stepwise setting with a step of 0.1V in the range of 0.9V to 4.0V is possible. c 1 : Fixed d C : Fixed e Designation of Taping Type: TR (R efer to Taping Specifications)

However, when the wire connected VIN is long, use a capacitor. Output noise can be reduced with using capacitor. Insert capacitors with the capacitance of 0.1 µF to 2.2 µF between input/output pins and GND pin as close as possible.
