ISL9011IRGCZ-T

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

The ISL9011IRGCZ-T is a dual low-dropout (LDO) linear voltage regulator manufactured by Intersil, now part of Renesas. It features two independent channels with fixed output voltages of 2.7V and 1.8V. The device supports maximum output currents of 150mA for the first channel and 300mA for the second. It operates within an input voltage range of 2.3V to 6.5V and maintains functionality across a temperature range of -40°C to +85°C. The component is housed in a compact 10-lead DFN (3x3mm) package.

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

• Dual-channel architecture providing independent 2.7V and 1.8V outputs
• Low quiescent current consumption for power efficiency
• High Power Supply Rejection Ratio (PSRR) performance
• Stable operation with ceramic capacitors having low ESR

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

• Portable electronic devices requiring multiple regulated rails
• Battery-powered systems needing low standby current
• Noise-sensitive analog circuits requiring clean power supplies
• Embedded systems utilizing single-cell lithium-ion batteries

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Procurement Notes

Verify the specific suffix 'IRGCZ-T' to confirm the 2.7V/1.8V output configuration and tape-and-reel packaging format. Ensure compatibility with the 10-DFN footprint during PCB layout. Confirm RoHS compliance status if required by your manufacturing standards. Cross-reference the manufacturer designation between Intersil and Renesas for accurate documentation access.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Selection Notes

Select this component when a dual-output LDO is required with asymmetric current capabilities. The 150mA/300mA split suits applications where one rail powers logic and another powers RF or analog sections. The fixed voltage options eliminate external resistor networks. Consider the 3x3mm DFN package for space-constrained designs requiring surface-mount assembly.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Part Context

This device belongs to the ISL9011 family of dual LDO regulators designed for high-performance portable applications. The series emphasizes low noise and high PSRR to support sensitive communication interfaces. The transition from Intersil to Renesas affects branding but not the core electrical specifications or pinout compatibility within the same product line.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Replacement Considerations

Check for ISL9011AIRKCZ variants which may offer different output voltages or temperature grades. Verify pin-to-pin compatibility before substituting with other dual LDOs from Renesas or third-party manufacturers. Ensure the replacement supports the required 300mA load on the secondary channel.
