LD59015C12R

Overview

The LD59015C12R is a fixed-output linear voltage regulator manufactured by STMicroelectronics, providing a stable 1.2V output with a maximum current capacity of 150mA. It operates within an input voltage range of 2.4V to 5.5V and features a typical dropout voltage of 150mV. The device incorporates low quiescent current consumption, high power supply rejection ratio (PSRR), and low noise characteristics. Integrated protection mechanisms include short-circuit constant current limiting and thermal shutdown. It is housed in a compact SOT-323-5 surface-mount package and supports operation across a temperature range of -40°C to 125°C.

Feature Summary

Logic-controlled electronic shutdown function for ultra-low power consumption
High power supply rejection ratio suitable for noise-sensitive applications
Internal overcurrent and thermal protection circuits
Compatible with ceramic capacitors for stability

Applications

Mobile phones
Personal digital assistants (PDAs)
Cordless phones
Battery-powered systems

Procurement Notes

Verify the specific suffix 'C12' confirms the 1.2V fixed output voltage variant. Confirm the 'R' suffix indicates tape-and-reel packaging. Check the component status as obsolete or NRND in official documentation before finalizing procurement plans due to potential end-of-life constraints.

Selection Notes

Select this component when a precise 1.2V rail is required from a 2.4V to 5.5V source. Ensure the application demands low noise and high PSRR. Verify that the SOT-323-5 footprint matches the design layout. Consider the 150mA limit against peak load requirements.

Part Context

This part belongs to the LD59015 family of low-noise, high-PSRR linear regulators. The base model offers various fixed output voltages ranging from 1.2V to 3.3V in 100mV steps. The LD59015C12R specifically denotes the 1.2V output version within this series, sharing common electrical characteristics and protection features with other variants.
