The SY20737H is a high-voltage input Linear Voltage Regulator (LDO) operating with input voltages from 4V to 36V and capable of delivering 500mA to a load, with ultralow ground current and low dropout voltage.
The SY20737H has an adjustable output that can be configured using two external resistors. The device offers protection features, including an over-current limit, output short and over-temperature protections.
The Enable input allows disabling the part to reduce power consumption. The High-Power Supply Rejection Ratio (PSRR) and low noise makes this part suitable for many applications in industrial and consumer products.
The SY20737H is available in a compact DFN 2mm×3mm-8pin package.
