LD6815TD/21H,125

Overview

The LD6815TD/21H,125 is a low-dropout regulator (LDO) from the NXP LD6815 series, providing a fixed nominal output voltage of 2.1 V. It operates with input voltages ranging from 2.3 V to 5.5 V and supports a maximum output current of 150 mA. The device features an ultra-high power supply rejection ratio (PSRR) of 75 dB at 1 kHz and a typical dropout voltage of 250 mV at full load. In disabled mode, it maintains a high-ohmic state at the output pin. The component is housed in a compact SOT753 (TSOP5) plastic package.

Feature Summary

Ultra-high power supply rejection ratio for effective noise suppression
Auto discharge or high-ohmic output stage options available
Low quiescent current consumption in shutdown mode
High-level electrostatic discharge protection

Applications

Smartphones
Tablet PCs
Mobile handsets
Portable media players

Procurement Notes

Verify the specific ordering suffix and marking code against the manufacturer's official documentation before procurement. Confirm that the selected variant matches the required output voltage tolerance and package orientation specifications. Ensure compliance with environmental directives such as RoHS and REACH requirements applicable to your region. Cross-reference the part number with the latest product status information to confirm availability and manufacturing lifecycle stage.

Selection Notes

Select this component when a stable 2.1 V rail is required from a variable input source between 2.3 V and 5.5 V. The high PSRR makes it suitable for sensitive analog circuits in portable devices. Consider the TSOP5 package size for space-constrained designs. Verify that the external capacitor ESR values fall within the specified range to ensure stability and proper shutdown behavior.

Part Context

This part belongs to the LD6815 series of low-dropout regulators designed for mobile and portable applications. The series offers various fixed output voltages and packaging options. The 'H' suffix indicates a high-ohmic output state in disable mode, distinguishing it from the 'P' variant which includes an auto-discharge function. All devices utilize monolithic silicon technology.
