Overview
Description
The ISL80510 is a single output Low Dropout voltage regulator (LDO) capable of sourcing up to 1A output current. This LDO operates from input voltages of 2. 2V to 6V. The output voltage of 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. This CMOS LDO consumes 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 ISL80510 provides 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 the part to be placed into a low quiescent current shutdown mode.

Is the ISL80510 a drop-in replacement for TPS7A8001?
Question: Can I use the ISL80510 to replace TPS7A8001 from Texas Instruments? Answer: The ISL80510 is pin-to-pin compatible with TI’s TPS7A8001 but it is not a 100% drop-in replacement - you will need to adjust either R1 or R2 (output voltage divider) to use. Our ISL80510 has ...

Do the ISL80505 and ISL80510 have current limit protection and thermal shutdown functions?
Question: Do these parts have current limit protection and thermal shutdown functions? Answer: Yes, they both have these features. Current Limit Protection: These LDOs incorporates protection against overcurrent due to any short or overload condition applied to the output pin. The LDO performs as a constant current source when the ...

Do I need to 2 separate capacitors on both VIN pins and also on both VOUT pins on the ISL80505 and ISL80510?
Question: On these parts there are 2 VIN pins (pins 7 and 8) and 2 VOUT pins (pins 1 and 2). Do I need a capacitor on each one of these pins for a total of 4 capacitors, or do I just need a one capacitor for both VIN pins ...
