Overview
The LD6815TD/12H,125 is a low dropout regulator (LDO) from NXP Semiconductors providing a fixed nominal output voltage of 1.2 V with a maximum load current of 150 mA. It operates within an input voltage range of 2.3 V to 5.5 V and features a typical dropout voltage of 250 mV at full load. The device incorporates high-ohmic state behavior in disabled mode and includes overcurrent protection. It achieves a power supply rejection ratio of 75 dB at 1 kHz and maintains an RMS output noise of 40 µV across the 10 Hz to 100 kHz frequency band.
Feature Summary
- Provides high-ohmic state at the output pin when set to disabled mode
- Integrates overcurrent protection for circuit safeguarding
- Delivers ultra-high power supply rejection ratio for effective noise suppression
- Features low quiescent current consumption during shutdown mode
Applications
- Smartphones
- Tablet PCs
- Mobile handsets
- Portable media players
Procurement Notes
Verify that the specific suffix '125' aligns with the manufacturer's standard packing quantity or reel specifications, as datasheet references indicate a packing quantity of 3000 units for the base type number. Confirm the package orientation matches the Q3 designation on the carrier tape. Ensure compliance with the specified external capacitor requirements for stability.
Selection Notes
Select this component for applications requiring a precise 1.2 V rail with minimal voltage drop under moderate loads. The high PSRR makes it suitable for sensitive analog sections in noisy environments. Consider the thermal resistance characteristics and PCB layout requirements to manage heat dissipation effectively within the operating temperature range.
Part Context
This part belongs to the LD6815 series of low dropout regulators designed for mobile and portable electronics. The series offers various fixed output voltages ranging from 1.2 V to 3.6 V. The 'H' suffix denotes the high-ohmic output configuration, distinguishing it from the pull-down variant. All devices utilize monolithic silicon technology and are housed in the compact SOT753 plastic package.
Replacement Considerations
Other members of the LD6815 series with different output voltages may serve as functional replacements if the voltage requirement differs. Verify compatibility regarding the disabled mode output impedance and ensure the replacement part supports the required input voltage range and load current specifications.
