Product Description
STMicroelectronics LDK320AU50R Voltage Regulator IC combines high reliability and efficient power management for modern electronic applications. Designed for use in battery-powered devices and circuit boards, it is suitable for both commercial and industrial projects where stable voltage output is crucial.
This low drop voltage regulator provides a maximum output current of 200mA from input voltages ranging between 2.5V and 18V. It boasts a typical dropout voltage of just 100mV at 100mA load, making it an excellent choice for low power situations.
The LDK320AU50R offers high PSRR of 88 dB at 120 Hz, guaranteeing low noise operation and consistent performance. Its quiescent current is typically 60μA, dropping to below 1μA in shutdown mode, which is ideal for energy-conscious designs.
Logic-controlled electronic shutdown and compatibility with ceramic capacitor (COUT = 1μF) further enhance flexibility and integration possibilities. Built-in current, SOA and thermal protections safeguard both the regulator and connected components.
Low dropout voltage ensures stable regulation. Wide input voltage range (2.5V - 18V) supports numerous power sources. Maximum output current 200mA handles various low-power loads. Enable logic control reduces power consumption in standby mode.
RoHS compliant for safe, sustainable electronic design.
Industrial, laboratory and commercial electronics benefit from these robust Voltage Regulator ICs, which can be used in sensor circuits, embedded controllers, automotive and power management assemblies.
