Overview
The AP7311-10WG-7 is a fixed-output low dropout linear regulator manufactured by Diodes Incorporated. It provides a stable 1.0V output with a maximum load current of 150mA. The device operates within an input voltage range of 2V to 6V and features a typical quiescent current of 65µA across the full load spectrum. It incorporates fast transient response capabilities, achieving a start-up time of 80µs. The regulator maintains stability using low ESR ceramic capacitors as small as 1µF. Built-in protections include current limiting, short-circuit protection, and thermal shutdown.
Feature Summary
- Integrated enable pin for active-high control of power states
- Fast transient response suitable for rapidly changing load conditions
- Stable operation with minimal low ESR ceramic output capacitors
- Comprehensive fault protection including current limit and thermal shutdown
Applications
- Battery powered devices
- Portable devices
- Notebook and desktop computers and peripherals
- CD-ROM, DVD and LAN cards
Procurement Notes
Verify that the specific suffix WG-7 corresponds to the SOT25 package in green molding compound with tape and reel packaging. Confirm the internal code '10' indicates the fixed 1.0V output variant. Ensure compliance requirements such as RoHS and lead-free finish are validated against the latest manufacturer documentation before finalizing procurement specifications.
Selection Notes
Select this component when a fixed 1.0V rail is required from a 2V to 6V source. It is appropriate for applications demanding low ground current and rapid recovery from standby modes. Verify that the expected load current remains below 150mA and that the input-to-output voltage differential allows for proper regulation within the specified dropout characteristics.
Part Context
This part belongs to the AP7311 series of low dropout regulators designed for portable electronics. The series offers both adjustable and fixed output options within the same package family. The AP7311-10WG-7 specifically denotes the fixed 1.0V version housed in the compact SOT25 footprint, targeting space-constrained mobile and peripheral applications.
Replacement Considerations
Cross-reference with other AP7311 variants for different fixed voltages or adjustable configurations. Verify pinout compatibility if substituting with similar LDOs from other manufacturers. Ensure replacement parts support the same 150mA load and 6V maximum input rating.
