The LDK120 is a low dropout regulator designed for applications requiring a stable 200 mA output with low noise and quiescent current. It operates from 1.9 to 5.5 V input, featuring very low dropout voltage (~100 mV at 100 mA), internal thermal and current limits, and optional external bypass capacitor stabilization. Its small form factor (DFN6, SOT23-5L, SOT323-5L packages) makes it ideal for battery-powered devices like mobile phones, PDAs, and digital cameras. The device includes a logic-controlled shutdown to minimize power consumption in standby mode, within temperature range -40°C to 125°C.
Fixed Output Voltages Available: 0.8 V to 3.5 V in 100 mV steps
Adjustable Output Voltage Range: 0.8 V to Vin - Vdrop
