EVVO, based in Hong Kong, is a pioneering semiconductor company specializing in power devices.

EVVOSEMI 78L05 is a voltage regulator that provides a stable 5V output with up to 100mA current from a higher input voltage.

EVVOSEMI's AMS1117 series is popular LDO regulators with fixed and adjustable versions, with features of thermal shutdown and current limiting, which is suitable for all electronic products.

EVVOSEMI TIP31C is an NPN power transistor with a 100V voltage rating and 3A current capacity. Suitable for audio,power linear and switching applications.The complementary PNP type is TIP32C.

EVVOSEMI’s LM2575/LM2575HV series are switcher voltage regulators offering fixed and adjustable outputs, easy design for power supply applications.

EVVOSEMI's XL1509 series is 150 KHz fixed frequency PWM step-down DC/DC converter, capable of driving a 3A load with high efficiency, low ripple, excellent line and load regulation.

EVVO's ULN2803A-EV Darlington transistor is a high-voltage, high-current driver IC with 8 NPN darlington pairs. Each unit shares a common emitter and features an open-collector output.

EVVO's MAX485ESA-EV has one driver and one receiver. The driver slew rates of the MAX485 is not limited, allowing them to transmit up to 2.5Mbps. They draw between 120µA and 500µA of supply current when unloaded or fully loaded with disabled drivers.

EVVO's DS18B20-EV digital thermometer supplies 9-bit to 12-bit readings and has an alarm function with nonvolatile user- programmable upper and lower trigger points.

The EVVO LM2596 series of regulators are monolithic integrated circuits that provide all the active functions for a step-down (buck) switching regulator, capable of driving a 3A load with excellent line and load regulation.
