Features: - High efficiency up to 89%. - Built in Frequency Compensation. - Built in Soft-Start Function. - Built in Thermal Shutdown Function. - Built in Current Limit Functio. Applications: ADC/DAC/Operational Amplifier Reference voltage. RS232 RS485 RS422 Bus. Audio equipment. Low power audio power supply. Car audio amplifier dual power. LCD power supply. Instrumentation equipment. Instrumentation multimeter. Note: 1. In order to obtain a more stable voltage, it is recommended that the output is greater than 15MA. 2. V- cannot be used alone, or no voltage output.But you can just use V+. 3. The startup current of the module is 2.5-3 times the operating current. 4. Increasing the 1UF-10UF MLCC capacitor reduces the startup current.
