ISL80505
ISL80505 is High Performance 500mA LDO manufactured by Renesas.
High Performance 500m A LDO
The ISL80505 is a single output Low Dropout voltage regulator (LDO) capable of sourcing up to 500m A output current. This LDO operates from input voltages of 1.8V to 6V. The output voltage of ISL80505 can be programmed from 0.8V to 5.5V.
A submicron Bi CMOS process is utilized for this product family to deliver the best in class analog performance and overall value. This CMOS LDO consumes significantly lower quiescent current as a function of load pared to bipolar LDOs, which translates into higher efficiency and packages with smaller footprints.
State-of-the-art internal pensation achieves a very fast load transient response and excellent PSRR. The ISL80505 provides an output accuracy of ±1.8% VOUT accuracy over all load, line and temperature variations (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 the part to be placed into a low quiescent current shutdown mode.
Table 1 shows the differences between the ISL80505 and others in its family.
