LDK130C15R

Overview

The LDK130C15R is a fixed-output linear voltage regulator manufactured by STMicroelectronics, providing a stable 1.5V output with a maximum current capacity of 300mA. It operates within an input voltage range of 1.9V to 5.5V and features a typical dropout voltage of 100mV at 100mA load. The device incorporates low quiescent current characteristics, drawing 60µA during operation and less than 1µA in shutdown mode when enabled. It includes internal protection mechanisms such as overcurrent limiting and thermal shutdown, ensuring reliability across a wide operating temperature range from -40°C to +125°C.

Feature Summary

Logic-controlled electronic shutdown function enables deep sleep mode for minimal power consumption
Internal constant current limiting and thermal protection safeguard against overload conditions
Compatible with small ceramic output capacitors for stable regulation in compact designs

Applications

Low-power battery-powered portable devices requiring extended runtime
Automotive electronics applications meeting AEC-Q100 Grade 1 standards
Always-on systems in body and interior control modules

Procurement Notes

Verify the specific suffix 'C' indicates the required package type and tape/reel configuration before ordering. Confirm that the fixed 1.5V output aligns with system requirements, as other voltages are available in the LDK130 family. Ensure compatibility with SOT-323-5 or equivalent footprint constraints during PCB layout planning.

Selection Notes

Select this component when a fixed 1.5V rail is needed with high efficiency under light loads due to low quiescent current. Consider the SOT-323-5 package for space-constrained layouts. Evaluate if the 300mA current limit suffices for peak loads, noting that higher current variants exist within the same product family.

Part Context

The LDK130 series represents a line of ultra-low-dropout regulators designed for automotive and industrial environments. These devices emphasize low noise and high precision, making them suitable for sensitive analog circuits. The C15R designation specifically identifies the 1.5V fixed output version packaged in SOT-323-5, optimized for surface-mount assembly processes.
