LDK120PU30R

Overview

The LDK120PU30R is a positive fixed linear low-dropout voltage regulator manufactured by STMicroelectronics. It provides a fixed output voltage of 3V with a maximum continuous output current of 200mA. The device operates within an input voltage range up to 5.5V and maintains stability using only a 1µF ceramic capacitor on the output. Key electrical specifications include a maximum dropout voltage of 0.3V at full load, a typical quiescent current of 60µA, and a power supply rejection ratio (PSRR) of 55dB across the 120Hz to 10kHz frequency band. It features logic-controlled enable functionality for shutdown modes.

Feature Summary

Ultra-low dropout performance ensures efficient regulation in battery-powered applications
Logic-controlled electronic shutdown minimizes total current consumption when disabled
Integrated protection mechanisms include constant current limiting and thermal shutdown

Applications

Low-power battery-operated consumer electronics
Portable devices requiring stable voltage rails
Always-on automotive body functions

Procurement Notes

Verify the specific suffix PU30R to confirm the 3V fixed output voltage and 6-DFN package configuration. Ensure compatibility with standard surface-mount assembly processes. Confirm RoHS3 compliance status if required by environmental regulations. Check lead times as manufacturing programs may undergo reshaping updates.

Selection Notes

Select this component when a fixed 3V rail is required with minimal external components. The 6-DFN package suits space-constrained designs. Verify that the input voltage does not exceed 5.5V. Consider the 60µA quiescent current for battery life calculations. Ensure the load current remains within the 200mA limit to maintain regulation accuracy.

Part Context

This part belongs to the LDK120 series of ultra-low dropout regulators designed for low noise and low power consumption. The series offers various fixed output voltages and adjustable versions. It utilizes advanced CMOS technology to achieve high performance in a compact footprint suitable for modern portable electronics.
