ISL9011IRBCZ-T

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

The ISL9011IRBCZ-T is a dual low-dropout (LDO) linear regulator manufactured by Renesas Electronics Corporation. It integrates two independent LDO channels within a compact 10-lead, 3mm x 3mm Dual Flat No-Lead (DFN) package. Channel 1 provides a fixed output voltage of 1.5V with a maximum continuous current capability of 150mA. Channel 2 delivers a fixed output voltage of 1.8V with a maximum continuous current capability of 300mA. The device operates from an input supply voltage range of 2.3V to 6.5V and maintains stable regulation across an operating temperature range of -40°C to +85°C.

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

How does the device manage startup sequences between the two channels?

The ISL9011 prioritizes Channel 1 during simultaneous enablement. If both enable pins are asserted together, VO1 powers up first. If only one pin is active, that channel ramps up independently.

What is the function of the CBYP pin?

The CBYP pin serves as the reference bypass terminal. Connecting a capacitor here allows users to tune the noise filter performance, improving PSRR and reducing output noise for sensitive applications.
