LD6815TD/18H,125

Overview

The NXP LD6815TD/18H,125 is a low dropout regulator (LDO) with a fixed nominal output voltage of 1.8 V and a maximum output current of 150 mA. It operates within an input voltage range of 2.3 V to 5.5 V. The device features a typical power supply rejection ratio (PSRR) of 75 dB at 1 kHz and a typical dropout voltage of 250 mV at full load. It exhibits a quiescent current of 0.1 µA in shutdown mode and provides high-level electrostatic discharge protection rated at 6 kV under the Human Body Model.

Feature Summary

High-ohmic state at the output pin when disabled
Ultra-high power supply rejection ratio for noise suppression
Low quiescent current consumption during shutdown
Integrated overcurrent protection mechanisms

Applications

Smartphones
Tablet PCs
Mobile handsets
Portable media players

Procurement Notes

Verify the specific suffix 'H' indicates the high-ohmic output configuration rather than the pull-down variant. Confirm the package type matches the SOT753 (TSOP5) specification. Ensure environmental compliance requirements align with the manufacturer's material declarations. Cross-reference the marking code AC5 on the component body to validate authenticity against official datasheet tables.

Selection Notes

Select this component when a stable 1.8 V rail is required from varying input sources between 2.3 V and 5.5 V. The high PSRR makes it suitable for sensitive analog sections in noisy environments. Choose this part over the 'P' suffix version if a high-impedance output state is preferred during disable cycles to prevent unintended loading on the downstream circuitry.

Part Context

This device belongs to the LD6815 series of small-size LDO regulators manufactured using monolithic silicon technology. The series is designed for portable applications requiring efficient power management within a minimal footprint. It shares common electrical characteristics with other variants in the family, differing primarily in output voltage settings and output stage behavior upon deactivation.
