Overview
The LF90ABPT-TR is a positive fixed output linear voltage regulator from STMicroelectronics. It delivers a stable 9V output with a maximum output current of 500mA. The device features very low dropout voltage characteristics and includes an inhibit function for power management control. It is housed in a PPAK package, designed for efficient thermal performance and compact board space utilization in portable and battery-powered applications.
Feature Summary
- Provides a fixed 9V regulated output voltage
- Supports up to 500mA load current
- Integrates an inhibit pin for shutdown control
- Utilizes PPAK packaging for enhanced thermal dissipation
Applications
- Battery-powered portable electronics
- Low dropout power supply circuits
- Embedded systems requiring stable 9V rails
- Inhibit-controlled power management modules
Procurement Notes
Verify the exact suffix (e.g., -TR) matches your reel quantity requirements. Confirm the PPAK package type aligns with your PCB footprint. Ensure the 9V fixed output meets your system voltage needs. Check for RoHS compliance status if required by your manufacturing standards. Validate supplier authenticity through authorized channels.
Selection Notes
Choose this component when a fixed 9V output is required without external resistor networks. Consider the 500mA current limit against your peak load demands. Evaluate the PPAK package for thermal constraints in enclosed designs. The inhibit feature offers additional control flexibility compared to standard LDOs. Verify input voltage range compatibility with your source.
Part Context
This part belongs to STMicroelectronics' Linear Voltage Regulators - Low Drop Out (LDO) category. It is specifically designed as a very low drop voltage regulator with inhibit functionality. The product line targets applications needing reliable, compact power regulation with minimal component count.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Consult official STMicroelectronics resources or distributor cross-reference tools for compatible alternatives.
