Overview
The LA59700MC-AE is a positive adjustable linear low-dropout (LDO) voltage regulator manufactured by onsemi. It provides an output current capability of 1A with an output voltage range of 1.5 V to 13.5 V. The device features a chip enable function for power management control and operates with a maximum input voltage of 15V. It is housed in an 8-SOP surface-mount package, designed for applications requiring stable regulated power supplies with efficient thermal performance.
Feature Summary
- Positive adjustable output voltage regulation
- Integrated chip enable control function
- High output current capability of 1A
- Surface-mount 8-SOP packaging
Applications
- Battery-powered portable devices
- Industrial control systems
- Consumer electronics power supplies
Procurement Notes
Verify the specific suffix 'AE' against official onsemi documentation to confirm pinout and electrical specifications, as variations exist within the LA59700 family. Confirm availability status, as some variants may be discontinued or subject to supply constraints. Ensure the selected package matches the PCB footprint requirements for the 8-SOP form factor.
Selection Notes
Select this component when a fixed 1A LDO is insufficient and adjustable output is required up to 13.5V. Consider the 15V maximum input rating and ensure the dropout voltage characteristics meet the system's minimum input-output differential requirements at the expected load current.
Part Context
This part belongs to the LA59700 series of linear regulators from onsemi, formerly associated with Fairchild Semiconductor. The series includes various suffixes indicating different packages or temperature grades. The LA59700MC-AE specifically denotes the adjustable version in the 8-SOP package, distinct from fixed-voltage variants.
Replacement Considerations
Direct substitutes include other parts within the LA59700 family such as LA59700MC-AH, provided the pinout and electrical parameters are identical. Verify compatibility with any fixed-voltage alternatives if the application design allows for modification of the output setting.
