ICL7663AESA+

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

The ICL7663AESA+ is a micropower linear voltage regulator manufactured by Analog Devices Inc./Maxim Integrated. It provides an adjustable positive output voltage ranging from 1.3 V to 16 V with a maximum output current of 40 mA. The device features a low quiescent current of 4 µA and operates within an input voltage range of 1.5 V to 16 V. It is housed in an SOIC-8 surface-mount package and supports an extended industrial temperature range from -40°C to +85°C.

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

Verify the specific suffix 'A' indicates the extended temperature grade (-40°C to +85°C) compared to commercial variants. Confirm RoHS compliance status as datasheets may vary by production batch. Ensure the SOIC-8 footprint matches the PCB design constraints before finalizing procurement orders.

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

Select this component when low standby current is critical for extending battery life in portable devices. The adjustable output allows flexibility in setting precise voltage levels without requiring multiple fixed-voltage regulators. Consider the thermal dissipation capabilities given the 40 mA output limit and SOIC-8 package size.

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

This part belongs to the ICL7663 series of micropower linear regulators. It shares functional similarities with other Maxim Integrated LDOs but is distinguished by its specific quiescent current profile and adjustable output architecture. The 'A' suffix typically denotes industrial temperature grading, differentiating it from commercial grade counterparts like the standard ICL7663.

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

Direct substitutes include the ICL7663BCSA (commercial grade, limited to 0°C to +70°C) or the MAX663ESA+ (dual mode, slightly different electrical characteristics). Verify pin compatibility and thermal requirements when cross-referencing with other SOIC-8 LDOs.
