Intersil’s New LDO Regulators Provide Best-in-Class Dropout and Transient Performance for Sensitive Loads. The ISL80505 delivers clean output voltage to CPUs, DSPs and MCUs.

These high performance single output low-dropout (LDO) voltage regulators provide best-in-class dropout and transient performance for noise sensitive loads. The ISL80505 delivers 0.5A of continuous output current and ultra-low dropout of 45mV at full load.

Intersil’s ISL80505 LDOs provide better transient performance with peak-to-peak excursions up to nine times lower than competitive LDOs. This transient performance level and DC accuracy of 1.8% safeguards against voltage undershoots and overshoots to deliver clean point-of-load voltage to CPUs, DSPs and MCUs, which require tight voltage accuracy and low noise. The ISL80505’s compensation loop provides excellent noise filtering by maintaining a flat power supply rejection ratio (PSRR) response over a wide range of frequencies.

Features:

• Single-output LDO voltage regulator enables ultra-low dropout of 45mV at Vout of 2.5V with a 500mA load.
• Stable operation with a small 4.7μF output ceramic capacitor
• Delivers ±1.8% Vout accuracy guaranteed over line, load and junction temperature range of -40°C to +125°C
• Programmable output soft-start supports sequencing and helps power supply designer control inrush current
• Current limit protection and thermal shutdown protects against high load current or operating temperature.
