STMicroelectronics, Inc. LDO Voltage Regulators LDK220U50R

The LDO, Fixed, 5V, 0.2A, -40 to 125¬8C from STMicroelectronics is a low-dropout voltage regulator designed to provide a maximum output current of 200 mA. It operates with an input voltage range of 2.5 V to 13.2 V and features a typical dropout voltage of 100 mV at 100 mA load. The device has a low quiescent current of approximately 55 ¬µA and can achieve a total current consumption of less than 1 ¬µA in shutdown mode. This LDO is suitable for battery-powered applications due to its low noise characteristics and compatibility with ceramic capacitors, requiring only a 1 ¬µF output capacitor for stabilization. It includes internal current and thermal limiting features for enhanced reliability. The output voltage tolerance is ¬±2.0% at 25 ¬8C, ensuring stable performance. The product is available in multiple package options, including SOT23-5L, SOT323-5L, SOT-89, and DFN6-1.2x1.3.
