Overview
The LD39015XG10R is a low dropout linear voltage regulator manufactured by STMicroelectronics. It provides a fixed output voltage of 1 V with a maximum output current of 150 mA. The device operates within an input voltage range of 1.5 V to 5.5 V and features a typical dropout voltage of 80 mV at 100 mA load. It exhibits very low quiescent current, typically 18 μA at no load, and includes logic-controlled electronic shutdown for reduced consumption below 1 μA. The regulator is stable with ceramic capacitors and offers power supply rejection of 65 dB at low frequencies.
Feature Summary
- Ultra-low dropout voltage operation ensures efficient power delivery under varying load conditions.
- Logic-controlled enable function allows precise management of power states and minimizes standby consumption.
- Integrated short-circuit constant current limiting and thermal protection safeguard the device during fault conditions.
Applications
- Mobile phones
- Personal digital assistants (PDAs)
- Cordless phones
Procurement Notes
Verify the specific package type SOT-666 against design requirements. Confirm the fixed 1 V output voltage matches system needs. Ensure compatibility with ceramic output capacitors as specified in the datasheet. Check for any obsolete status indicators from the manufacturer before finalizing procurement plans.
Selection Notes
Select this component for battery-powered applications requiring low noise and high efficiency. The low quiescent current extends battery life significantly. The wide input voltage range accommodates various power sources. Ensure the thermal environment supports the operating temperature range of -40 °C to 125 °C.
Part Context
This part belongs to the LD39015 series of low dropout regulators. The series is designed for low power applications with emphasis on low noise and low quiescent current. The XG suffix indicates the specific package configuration, distinguishing it from other variants like M or J which may have different pinouts or packages.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Verify electrical compatibility and pinout alignment if considering alternative LDO regulators from other manufacturers.
