STMICROELECTRONICS LDK320AM33R Low Dropout Voltage Regulator

The LDK320 is a high-accuracy, low dropout voltage regulator capable of supplying up to 200 mA with an input voltage range of 2.5 to 18 V. It features very low dropout voltage of approximately 100 mV at 100 mA load, high power supply rejection ratio of 88 dB at 120 Hz, low noise, and a wide output voltage range from 1.2 V to 12 V on request. The device offers excellent thermal, current, and short-circuit protections, making it ideal for battery-powered applications with a compact SOT-23-5L or SOT-89 package, supporting wide temperature ranges from -40°C to 125°C.
