ISL78302ARNBZ-T7A - Renesas Electronics

Description: ISL78302 is a high performance dual LDO capable of sourcing 300mA current from each output. It has a low standby current and is stable with an output capacitance of 1µF to 10µF and an ESR of up to 200mΩ. The POR delay for VO1 is internally fixed at approximately 2ms. A reference bypass pin is also provided for connecting a noise filtering capacitor for low noise and high-PSRR applications. The quiescent current is typically only 47µA with both LDOs enabled and active. Separate enable pins control each indiv

ISL78302ARNBZ-T7A Frequently Asked Questions (FAQs)

  • Renesas provides a recommended PCB layout guide in their application note AN1995, which includes guidelines for thermal vias, copper pours, and component placement to minimize thermal resistance and ensure reliable operation.
  • To ensure reliable startup and shutdown, it's essential to follow the recommended power-up and power-down sequencing in the datasheet. Additionally, ensure that the input voltage ramps up and down slowly (typically 10ms to 100ms) to prevent inrush currents and voltage overshoots.
  • While the datasheet specifies the maximum input voltage rating, it's essential to ensure that the input voltage ripple is within the recommended range (typically 1% to 5% of the input voltage) to prevent oscillations, noise, and reduced performance.
  • To optimize the device for low-power operation, ensure that the input voltage is as low as possible while still meeting the minimum input voltage requirement. Additionally, consider using the device's power-saving features, such as the shutdown mode, and optimize the output voltage and current settings for the specific application.
  • Renesas provides guidelines for EMI filtering and shielding in their application note AN1965, which includes recommendations for input and output filtering, PCB layout, and shielding techniques to minimize electromagnetic interference and ensure reliable operation.
