IC chooser (quick guide)
| Design need | IC type to look for | Notes |
|---|---|---|
| Clean up / amplify sensor signals | Op-amp (e.g. LM358) or comparator | Use rail-to-rail and single-supply parts when working from 5V/3.3V. |
| Create clocks, delays, PWM | 555 timer or logic counters | Great for LED flashers, tone generation, and simple timing circuits. |
| Drop 12V/9V to 5V/3.3V | Linear regulators (7805, LDO) or DC-DC | Use DC-DC for higher current/efficiency, linear for low-noise small loads. |
| Drive motors, relays, solenoids | H-bridge or driver array (ULN2xxx) | Offload current from microcontroller pins; respect voltage/current ratings. |
| Add more I/O pins or shift levels | I²C/SPI expanders & level shifters | Ideal when using ESP32/ESP8266 or Raspberry Pi with 3.3V logic. |
These are typical starting points; always check each product’s datasheet for exact voltage, current, and package details.

FAQ
Are these ICs compatible with Arduino/ESP32/Raspberry Pi?
Yes—most run from 3.3–5V and expose standard logic/analog pins. Just respect voltage limits and use level shifting when needed.
How do I know if a regulator or driver can handle my load?
Check the datasheet for max current, power dissipation, and thermal limits. Leave margin (20–30%) above your expected load.
What package should I choose (DIP vs SMD)?
DIP is easier for breadboards and beginners; SMD is better for compact PCBs and production designs.
Do you ship nationwide?
Yes—fast shipping anywhere in the Philippines. Same-day processing on in-stock orders before cutoff.
