ISL9008IEBZ-T

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

The ISL9008IEBZ-T is a fixed-output low-dropout (LDO) linear voltage regulator manufactured by Renesas Electronics. It provides a stable 1.5 V output with a maximum load current of 150 mA. The device operates within an input voltage range of 2.3 V to 6.5 V and features a typical dropout voltage of 300 mV at full load. Key electrical characteristics include a quiescent current of 46 µA, a line regulation of 0.1%, and a load regulation of 0.1%. The unit is housed in a compact SC-70-5 surface-mount package and is rated for operation over an extended temperature range from -40°C to +85°C.

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

• Low noise architecture designed for sensitive analog and RF circuitry
• High power supply rejection ratio (PSRR) for effective ripple attenuation
• Ultra-low quiescent current to minimize standby power consumption
• Fixed output voltage configuration eliminates external resistor networks

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

• Portable battery-powered consumer electronics
• RF front-end modules requiring clean power supplies
• Microcontroller core voltage regulation
• Sensor interface circuits demanding low noise

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

Verify the specific suffix 'EB' confirms the 1.5 V fixed output variant, as the ISL9008A series utilizes alphabetical codes for different voltages. Confirm the 'T' suffix indicates tape-and-reel packaging if reel quantity is required. Check current lifecycle status on the manufacturer website, as older Intersil/Renesas parts may be subject to discontinuation or obsolescence notices. Ensure ESD handling precautions are followed during assembly due to the small SC-70-5 package size.

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

Select this component when a fixed 1.5 V rail is needed with minimal board space constraints. The SC-70-5 package offers a small footprint suitable for dense layouts. Consider the 150 mA current limit against peak load requirements; higher current variants exist in the same family. Verify that the input voltage remains above the minimum threshold of 2.3 V under all operating conditions to maintain regulation. Evaluate thermal performance based on the power dissipation calculated from the voltage drop and load current.

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

This part belongs to the ISL9008A family of low-noise LDO regulators originally developed by Intersil and later integrated into Renesas Electronics' portfolio. The family shares common architectural features such as high PSRR and low IQ but varies by output voltage and package type. Similar parts in the lineup include the ISL9008AIRUMZ-T (1.5 V, uTDFN6) and other voltage variants like the ISL9008AIECZ-T (1.8 V). The product represents a transition point where legacy Intersil designations were mapped to Renesas part numbers.

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

Publicly confirmed direct substitutes for the ISL9008IEBZ-T are not available in the provided documentation. Designers should consult the official Renesas ISL9008A datasheet for alternative pin-compatible options within the same family, such as the ISL9008AIRUMZ-T for a 1.5 V output in a different package, or verify cross-reference data through authorized distributor channels.
