LM3909 LED FlasherOscillator General Description The LM3909 is a monolithic oscillator specifically designed to flash Light Emitting Diodes. By using the timing capacitor for voltage boost, it delivers pulses of 2 or more volts to the LED while operating on a supply of 1. 5V or less. The circuit
LM79XX 5 Electrical Characteristics (LM7909) (Continued) (VI 15V, IO 500mA, 0C TJ 125C, CI 2. 2F, CO 1F, unless otherwise specified. ) Note: 1. Load and line regulation are specified at constant junction temperature. Changes in VO due to heating LM386 Basics. The LM386 is quite a versatile chip. Only a couple resistors and capacitors are needed to make a working audio amplifier. The chip has options for gain control and bass boost, and it can also be turned into an oscillator capable of outputting sine waves or square waves. lm7909 pdf Electrical Characteristics (LM7909) (Continued) (VI 15V, IO 500mA, 0C TJ 125C, CI 2. 2F, CO 1F, unless otherwise specified. ) Note: 1. Load and line regulation are specified at constant junction temperature. Changes in VO due to heating effects must be taken into account separately. Pulse testing with low duty is used.
