LDK320AM33R Description

Short technical summary and product information.

The LDK320AM33R from STMicroelectronics is a high-performance linear voltage regulator designed for various applications requiring a stable 3.3V power supply. It can deliver up to 200mA of output current with a low dropout voltage of 0.35V at 200mA, ensuring efficient power regulation.

 

This device operates with an input voltage range up to 18V and exhibits a low quiescent current of 90µA, making it suitable for battery-powered devices. Protection features include over-current and over-temperature shutdown, enhancing reliability. The regulator also offers good power supply rejection ratio (PSRR) across a frequency range of 120Hz to 10kHz.

 

Packaged in a compact SOT-23-5 (SC-74A, SOT-753) surface-mount case, the LDK320AM33R is ideal for space-constrained designs. Its operating temperature range is -40°C to 125°C (TJ), allowing for use in demanding environments. The device features an Enable pin for control, providing flexibility in power management strategies.
