RT9018C - Ultra Low Dropout Regulator

General Description

The RT9018C is a high performance positive voltage regulator designed for use in applications requiring very low input voltage and very low dropout voltage at up to 3A (Peak).

It operates with a VIN as low as 1.4V and VDD voltage 3V with output voltage programmable as low as 0.8V.

Key Features

  • Maximum 3A Low Dropout Voltage Regulator.
  • High Accuracy Output Voltage ±1.5%.
  • Typically 210mV Dropout at 3A.
  • Power Good Output.
  • Output Voltage Pull Low Resistance when Disable.
  • Thermal and Over Current Protection.
  • RoHS Compliant and Halogen Free.

RT9018C Maximum 3A, Ultra Low Dropout Regulator General Description The RT9018C is a high performance positive voltage regulator designed for use in applications requiring very low input voltage and very low dropout voltage at up to 3A (Peak). It operates with a VIN as low as 1.4V and VDD voltage 3V with output voltage programmable as low as 0.8V. A significant feature includes ultra low dropout, which is ideal for applications where VOUT is very close to VIN. Additionally, there is an enable pin to further reduce power dissipation while shutdown. The RT9018C provides excellent regulation over variations in line, load and temperature. It also provides a power good signal to indicate whether the voltage level of VOUT has reached 90% of its rating value.
