ICL7663SCPAZ

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

The ICL7663SCPAZ is a micropower adjustable positive linear voltage regulator manufactured by Renesas Electronics Corporation. It utilizes CMOS technology to achieve low quiescent current, typically 12 uA, making it suitable for battery-operated systems. The device provides an output voltage range from 1.3 V to 16 V with a maximum output current of 40 mA. It features a line regulation of 0.03 %/V and operates within a temperature range of 0°C to +70°C. The component is housed in an 8-pin PDIP package designed for through-hole mounting.

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

Verify the specific suffix 'Z' indicates RoHS compliance status as per manufacturer documentation. Confirm the PDIP-8 package type matches your PCB footprint requirements. Check for End-of-Life notices or obsolescence warnings directly from Renesas before finalizing design-in decisions. Ensure thermal management aligns with the specified operating temperature limits.

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

Select this component when low quiescent current is critical for system efficiency. The adjustable output allows flexibility in setting precise voltage levels using external resistors. Consider the 40 mA output limit for load requirements. The through-hole PDIP package is suitable for prototyping or applications where surface-mount options are not preferred.

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

This part belongs to the ICL7663 series of micropower linear regulators. It is distinct from charge pump variants like the ICL7660. The series focuses on low-power linear regulation rather than switching topologies. Renesas continues to support legacy Intersil products under this branding.

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

Direct pin-to-pin replacements may include other CMOS adjustable linear regulators with similar current and voltage specifications. Verify that alternative parts maintain the same quiescent current profile and package dimensions. Cross-reference datasheets for exact electrical parameter matching.
