LDK120C25R

Overview

The LDK120C25R is a fixed-output linear low-dropout regulator (LDO) manufactured by STMicroelectronics. It provides a fixed output voltage of 2.5V with a maximum continuous output current of 200mA. The device operates within an input voltage range of 1.9V to 5.5V and features a typical dropout voltage of 100mV at 100mA load. Quiescent current is specified at a maximum of 60µA, while the shutdown mode consumption is less than 1µA. It includes internal overcurrent and thermal protection mechanisms and is housed in a SOT-323-5 surface-mount package.

Feature Summary

Ultra-low dropout voltage performance for efficient power management
Logic-controlled electronic shutdown function for extended battery life
Integrated short-circuit constant current limiting and thermal protection

Applications

Low-power battery-powered consumer electronics
Portable devices requiring stable voltage regulation
Embedded systems with strict power consumption constraints

Procurement Notes

Verify the specific suffix 'C25R' to confirm the fixed 2.5V output voltage and SOT-323-5 packaging configuration. Ensure compatibility with ceramic output capacitors as required for stability. Confirm RoHS3 compliance status if environmental regulations apply to your manufacturing process. Cross-reference the manufacturer part number against distributor listings to avoid confusion with adjustable variants or different package options within the LDK120 family.

Selection Notes

Select this component when a precise 2.5V rail is required from a supply ranging between 1.9V and 5.5V. It is suitable for applications prioritizing low noise and minimal quiescent current draw. Consider the SOT-323-5 footprint constraints during PCB layout. Evaluate the thermal dissipation requirements based on the expected load current and ambient temperature conditions to ensure operation within the -40°C to 125°C range.

Part Context

The LDK120C25R belongs to the LDK120 series of ultra-low dropout voltage regulators designed for low-power applications. This series offers high precision and low noise characteristics, making it ideal for sensitive analog circuits. The C25R designation specifically indicates the fixed 2.5V output variant packaged in SOT-323-5, distinguishing it from adjustable versions or other fixed voltage outputs in the same family.
