ICL7663SIBA

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

The ICL7663SIBA is a positive linear voltage regulator manufactured by Intersil, now part of Renesas Electronics. It features an adjustable output voltage range from 1.3 V to 16 V with a maximum output current of 40 mA. The device operates within an input voltage range of 1.5 V to 16 V and maintains a low quiescent current of 12 uA. It offers a line regulation of 0.03 %/V and functions reliably across a temperature range of 0°C to +70°C. The component is housed in an SOIC-8 surface-mount package.

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

Verify the specific suffix 'BAZA' or 'SIBA' against official datasheets, as these often denote lead-free (Pb-Free) or anneal specifications rather than functional changes. Confirm RoHS compliance status directly with the manufacturer or authorized distributors, as legacy Intersil parts may have varying environmental declarations depending on production date and region.

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

Select this component when a stable, adjustable positive voltage is required with minimal static power draw. Ensure the application input voltage remains within the 1.5 V to 16 V limit. Consider the thermal dissipation capabilities of the SOIC-8 package relative to the expected load current and ambient operating temperature constraints.

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

This part belongs to the ICL7663 series of CMOS linear regulators. Intersil was acquired by Renesas Electronics, which continues to support and distribute these legacy components. The series is designed for applications requiring simple, cost-effective voltage regulation with low noise and high stability characteristics typical of CMOS technology.

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

Check for direct pin-compatible alternatives such as the LM317 family or other adjustable LDOs from Renesas. Verify that replacement candidates match the 40 mA output current and 1.5 V minimum input voltage requirements.
