ISL9014AIRKCZ

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

The ISL9014AIRKCZ is a dual-output linear voltage regulator manufactured by Renesas Electronics Corporation. It provides two fixed positive output voltages of 1.8V and 2.85V, each capable of delivering up to 300mA of load current. The device operates with an input voltage range from 2.3V to 6.5V and features extremely low quiescent current consumption of 40µA. It incorporates comprehensive protection mechanisms including overcurrent limiting, thermal shutdown, soft-start functionality, and undervoltage lockout (UVLO). The component is housed in a compact 10-DFN (3x3mm) package with an exposed pad for efficient thermal dissipation.

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

• Integrates two high-performance LDOs within a single compact package
• Provides excellent transient response to large current steps
• Features high power supply rejection ratio (PSRR) for noise reduction
• Includes built-in thermal shutdown and overcurrent protection

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

• Portable electronic devices requiring multiple stable voltage rails
• Battery-powered systems prioritizing low standby current consumption
• Embedded control circuits needing clean power for sensitive analog sections
• Communication modules requiring high PSRR performance

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

Verify the specific suffix KCZ to confirm the 1.8V/2.85V output configuration before procurement. Confirm RoHS3 compliance status as required by project specifications. Check for End-of-Life (EOL) notices or Product Change Notifications (PCNs) regarding manufacturing origin or labeling updates. Ensure compatibility with standard surface-mount assembly processes for 10-DFN packages.

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

Select this component when a dual-rail solution is needed to save board space compared to using separate regulators. The 300mA per channel rating suits moderate load applications. Consider the 1.8V/2.85V combination specifically if these are the primary logic and I/O voltages required. Evaluate the 40µA quiescent current against system battery life requirements. Verify that the 6.5V maximum input voltage aligns with the available supply rail.

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

This part belongs to the ISL9014A series of dual LDO regulators designed for low-noise and low-power applications. It shares the same core architecture and protection features as other variants in the family but differs in fixed output voltage combinations and packaging options. The series is characterized by its ability to maintain stability with small ceramic capacitors while offering high PSRR across a wide frequency range.
