The SY20725 is an efficient, precise low-dropout (LDO) regulator designed for high input voltage and ultra-low quiescent current applications.
The SY20725 provides adjustable output voltage with ±2% accuracy and very low dropout (300mV at 300mA). It also features optimized internal compensation, overcurrent protection, and thermal shutdown for stable operation when using low-ESR ceramic or tantalum capacitors.
The device can be enabled by driving the EN pin above the VEN_H threshold (1.5V) and disabled by driving EN below VEN_L (0.4V).
Only the divider resistors, input capacitor, and output capacitor need to be selected for the targeted application.
SY20725 is available in a compact SOT23-5 package.
