ICL7663AESA+T

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

The ICL7663AESA+T is a precision voltage converter IC manufactured by Analog Devices Inc. (formerly Maxim Integrated). It functions as a charge pump to generate negative supply voltages from positive inputs, typically converting +5V to -5V with high efficiency. The device operates over an extended temperature range and features low quiescent current consumption. Key electrical parameters include an output voltage accuracy of ±1% and a maximum output current capability suitable for biasing operational amplifiers or other analog circuits requiring dual supplies.

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

Verify the suffix '+T' indicates tape-and-reel packaging when ordering. Confirm the 'A' grade specifies the extended temperature range and tighter performance specifications compared to standard grades. Ensure the manufacturer designation matches Analog Devices Inc., as Maxim Integrated products are now part of ADI. Check for RoHS compliance markings on the datasheet or product page.

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

Select this component when an inductor-less solution for generating negative voltage is required. Consider the maximum output current requirements of the load circuit against the IC's capabilities. Evaluate the input voltage range to ensure compatibility with the system's power source. Compare quiescent current specs if battery life is a critical constraint in the design.

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

This part belongs to the ICL7660/ICL7662/ICL7663 family of voltage converters. These devices were originally developed by Maxim Integrated before its acquisition by Analog Devices Inc. The ICL7663 variant specifically offers improved performance characteristics such as higher efficiency and lower noise compared to earlier generations in the series.

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

Direct pin-compatible replacements may include the ICL7660 or ICL7662, though performance differences exist. Verify functional equivalence regarding output current and efficiency before substitution. Cross-reference with other charge pump ICs from different manufacturers only if pinout and electrical specifications match exactly.
