LD2982AM36R

LD2982AM36R Description

The LD2982AM36R is a linear voltage regulator designed by STMicroelectronics, a leading manufacturer in the electronics industry. This device is part of the Power Management Integrated Circuits (PMIC) category and is specifically tailored for applications requiring a fixed output voltage of 3.6V and a maximum output current of 50mA. The LD2982AM36R is housed in a compact SOT23-5 package, making it suitable for surface mount applications where space is a critical consideration.

This regulator is designed to operate with a maximum input voltage of1 6V, ensuring compatibility with a wide range of power sources. It features a low dropout voltage of 0.225V at 50mA, which allows it to maintain regulation even when the input voltage is close to the output voltage. This characteristic is particularly beneficial in battery-powered devices where the input voltage may drop significantly over time.

The LD2982AM36R also boasts a low quiescent current of 150 µA, which minimizes power consumption during standby or low-load conditions. This feature is crucial for extending battery life in portable electronic devices. Additionally, the regulator offers a high power supply rejection ratio (PSRR) of 45dB at 1kHz, effectively filtering out noise from the input power supply and ensuring a clean output voltage.
