Voltage Regulators - Linear, Low Drop Out (LDO) Regulators datasheet and documents for ISL6720AARZ

ISL6720AARZ

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Overview

The ISL6720AARZ is a triple linear bias supply IC from Renesas Electronics, designed for telecom and datacom applications. It features three outputs: an adjustable VIO (0V to 20V, up to 125mA) with back-bias capability, a switched regulated VSW (0V to 15V, 50mA), and a fixed continuous VCONT (5V, 25mA). The device supports a maximum input voltage of 100V and operates within a temperature range of -40°C to +105°C in an 11-DFN package.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Feature Summary

Provides three distinct output rails including an adjustable auxiliary winding regulator with 40V withstand capability.
Includes a delayed start feature for VIO and VSW outputs after the continuous output activates.
Incorporates two-stage over-temperature protection for enhanced reliability.
Package design complies with IPC2221A creepage and clearance spacing requirements.
