Overview
The LA59700MC-AH is a linear voltage regulator IC manufactured by onsemi, designed to provide positive adjustable voltage output up to 1A. It operates within an input voltage range of 8V to 15V and delivers an adjustable output from 1.25V to 13.5V. The device features a chip enable function for power management and is housed in an 8-SOP (Small Outline Package) suitable for surface mount applications.
Feature Summary
- Provides positive adjustable voltage regulation with a maximum output current of 1A
- Includes a dedicated chip enable function for efficient power control
- Operates reliably across a wide input voltage range from 8V to 15V
Applications
- General purpose linear power supply circuits
- Battery-powered devices requiring stable voltage regulation
- Embedded systems needing adjustable voltage rails
Procurement Notes
Verify the exact package variant and suffix compatibility before ordering, as manufacturing sources may vary. Confirm current availability status directly with authorized distributors or onsemi, as lead times and stock levels fluctuate. Ensure the specific orderable part number matches your design requirements regarding thermal performance and pin configuration.
Selection Notes
Select this component when a simple, low-noise linear regulation solution is required for currents up to 1A. It is suitable for designs where efficiency is less critical than cost and simplicity compared to switching regulators. Ensure the input-to-output voltage differential allows for adequate thermal dissipation within the 8-SOP package constraints.
Part Context
This part belongs to onsemi's portfolio of analog power management integrated circuits. It serves as a standard adjustable regulator option for consumer electronics and industrial equipment. The LA59700 series is designed to replace older bipolar regulator technologies with more modern surface-mount compatible packages.
Replacement Considerations
Check for direct pin-compatible alternatives such as the LA59700MC without the AH suffix if available. Verify that any substitute maintains the same 1A output current capability and 15V maximum input rating to ensure circuit compatibility.
