SE555FKB Frequently Asked Questions (FAQ)

  • The recommended operating voltage range for the SE555FKB is 4.5V to 15V, although it can operate up to 18V with reduced performance.

  • To ensure reliable oscillator startup, connect a 1kΩ to 10kΩ resistor between pin 2 (trigger) and pin 6 (threshold), and a 0.01μF to 0.1μF capacitor between pin 2 and ground.

  • The SE555FKB can operate up to 2.1MHz, but the maximum frequency is dependent on the values of the external resistors and capacitors used in the oscillator circuit.

  • While the SE555FKB can be used as a voltage regulator, it's not recommended due to its limited current sourcing capability (200mA) and lack of built-in voltage regulation features. A dedicated voltage regulator IC is a better choice.

  • To reduce power consumption, use a lower operating voltage, minimize the value of the resistors in the oscillator circuit, and consider using a CMOS version of the 555 timer (e.g., TLC555) which has lower power consumption.
