RN5RF Series

10V Input Voltage Regulator with External Tr.

  • Consumer
  • RoHS

The RN5RF Series are CMOS-based LDO regulators with external power transistor. By using an external PNP transistor, a low dropout voltage regulator ranging from several tens of mA to several hundreds mA can be configured. (Use a low saturation type PNP transistor with hFE of approximately 100 to 300.) RN5RF is available in SOT-23-5 package.
