RP109 Series

Low Voltage 150mA LDO Regulator

  • Consumer
  • PLP
  • RoHS

The RP109 Series are CMOS-based LDO regulators featuring 150mA output. The input voltage (VIN) is as low as Min. 1.4V and the output voltage can be set from 0.8V. RP109 Series features an excellent line transient response, ripple rejection at 75dB, and low noise. The output voltage accuracy has been improved to ± 1% and the temperature drift coefficient of the output voltage is as low as ± 30ppm/°C. In addition to SOT-23-5, SC-88A and DFN1010-4 packages, a 0.8mm square ultra compact DFN(PLP)0808-4 package is also available. RP109 Series contributes to the downsizing of the hand-held equipment because it can use the 0.1µF ceramic capacitor.
