Overview
The LD6806F/33H,115 is a fixed-output ultra low-dropout regulator (LDO) from the NXP LD6806 series. It provides a nominal output voltage of 3.3 V with a maximum continuous load current of 200 mA. The device operates within an input voltage range of 2.3 V to 5.5 V and features a typical dropout voltage of 60 mV at full load. It utilizes an SOT886 surface-mounted package and includes integrated thermal protection and current limiting circuits.
Feature Summary
- Ultra-low dropout performance ensures high efficiency and minimal power dissipation under heavy loads.
- Low noise operation suitable for sensitive analog and digital interface applications.
- Integrated enable pin allows for precise power management and system control.
- High-ohmic output state when disabled prevents leakage in multi-rail systems.
Applications
- Mobile phone handsets
- Cordless telephones
- Personal digital devices
Procurement Notes
Verify the specific suffix '115' against official documentation to confirm packaging details such as reel specifications or tape-and-reel quantities. Ensure the component matches the SOT886 footprint dimensions provided in the datasheet. Confirm that the high-ohmic output variant aligns with the system's disabled-state requirements.
Selection Notes
Select this component for designs requiring a compact LDO solution with low quiescent current. The SOT886 package is ideal for space-constrained mobile applications. Ensure the external load capacitance meets the minimum stability requirement of 0.7 µF with appropriate ESR characteristics.
Part Context
This part belongs to the LD6806 series of ultra low-dropout regulators designed for miniaturization. The series offers various output voltages and packages, including WLCSP4 and SOT753. The 'H' suffix denotes a high-ohmic output state upon disable, distinguishing it from the 'P' variant which features a pull-down transistor.
Replacement Considerations
Compatible alternatives within the same family include other LD6806 variants with different output voltages or package types, such as LD6806F/xxx or LD6806CX4/xxx. Verify pin compatibility and electrical specifications before substitution.
FAQ
What is the output state of the LD6806F/33H when the enable pin is low?
When the enable pin is low, the LD6806F/33H enters a high-ohmic state at the output pin, effectively disconnecting the output.
Does the LD6806F/33H require an external capacitor for stability?
Yes, the device requires an external load capacitance of at least 0.7 µF to guarantee stable regulator behavior.
