CW6202 is a high-performance, low-power, low dropout linear regulator (LDO). It is made for applications that need low power and small size. It has an ultra-low quiescent current (IQ) of only 1μA (typical), so it works well in battery-powered devices and can extend standby time.
Main Features:
Ultra-low quiescent current (1μA)
High output accuracy (±1.5%~±2%)
Low dropout voltage (100mV@100mA)
Wide input voltage range (2.5V~5.5V)
Optional fixed/adjustable output voltage
Key Specifications:
Max output current: 300mA / 500mA
Packages: SOT23-5, DFN-6 (small size)
Operating temperature: -40°C ~ +85°C
Performance Advantage:
In low-power scenarios like IoT sensors, CW6202’s 1μA IQ is over 50% lower than similar products. This helps improve battery life greatly.
