CS8391 overview
CS8391 is a component documented by Cherry Semiconductor Co. The PDF description identifies it as "5V/250mA, 5V/100mA Micropower Low Dropout Regulator with ENABLE." This guide condenses the most useful engineering information from the available PDF so that designers and sourcing teams can identify the checks that still need confirmation in the original document.

Specifications and operating details
The following points were extracted from the PDF text. Check the associated conditions, notes and limits in the complete document before using a value in a design.
- The switched primary output OUT1) supplies up to 250mA while the secondary (VOUT2) is capable of supplying 100mA.
- Both outputs have a maximum dropout voltage of 600mV and low reverse current.
- Quiescent current drain is typically 150µA when supplying 100µA from each output.
- With the primary output disabled, quiescent current drain is typically 100µA when supplying 100µA from the secondary output.
- 2V OUT1 5V regulated output which is activated by ENABLE input.
- OUT2 Standby output 5V, 100mA capability; always on.
- Measured when the output voltage has dropped 100mV from the nominal value obtained at 14V input, dropout voltage is dependent upon load current and junc- tion temperature.

Engineering review checklist
- Confirm the exact ordering code, package, pinout or terminal arrangement and document revision.
- Compare recommended operating conditions with absolute maximum ratings and retain adequate design margin.
- Validate electrical, thermal, mechanical and environmental behavior in the final application.
Always confirm values against the latest manufacturer-controlled datasheet, especially when qualifying a substitute or releasing a production BOM.
