Renesas Electronics ISL80505 & ISL80510 LDO Voltage Regulators
Renesas Electronics ISL80505 and ISL80510 LDO Voltage Regulators are single output Low Dropout voltage regulators capable of sourcing up to 500mA (ISL80505) or 1A (ISL80510) output current. The output voltage of the ISL80505 and ISL80510 can be programmed from 0.8V to 5.5V. A submicron BiCMOS process is utilized for this product family to deliver the best-in-class analog performance and overall value. These CMOS LDOs consume significantly lower quiescent current as a function of load compared to bipolar LDOs, which translates into higher efficiency and packages with smaller footprints. State-of-the-art internal compensation achieves a very fast load transient response and excellent PSRR.
The ISL80505 and ISL80510 provide an output accuracy of ±1. 8% VOUT accuracy over all load, line, and temperature variation (TJ = -40°C to +125°C). An external capacitor on the soft-start pin provides an adjustable soft starting of the output voltage ramp to control the inrush current. The ENABLE feature allows these devices to be placed into a low quiescent current shutdown mode.
The Renesas Electronics ISL80505 and ISL80510 LDO Voltage Regulators are available in a compact DFN-8 package with an exposed pad for improved thermal dissipation and noise immunity.
