STMICROELECTRONICS LDK220C40R Low Dropout Regulator

The LDK220 is a low dropout regulator capable of delivering up to 200 mA from input voltages ranging between 2.5 V and 13.2 V. Featuring a typical dropout voltage of 100 mV and low noise, it is ideal for battery-powered and portable devices. The device offers a wide range of output voltages, including fixed and adjustable options, and supports ceramic capacitors for stabilization. Its low quiescent current, thermal and current limits, and logic-controlled shutdown make it suitable for applications requiring high efficiency and minimal power consumption, such as smartphones, set-top boxes, and industrial equipment.
