l7805cv Regulated circuit diagram

Refer to the following figure, replace 78L05 with L7805CV, pin unchanged.

The typical application circuit of the lm7805 series integrated voltage regulator is shown in the figure below, which is a voltage regulator power supply circuit with a positive 5V DC voltage output. IC adopts integrated voltage regulator 7805, CC2 is the input and output filter capacitor, RL is the load resistance. When the output current is large, the 7805 should be equipped with a cooling plate.. Internal structure: Output power up to 30 watts, A VO is often 90 dB.

can be replaced directly. The LM1875 and TDA2030 (A) adopt the same TO220B package and have the same pin definition. In terms of parameters, the maximum voltage of LM1875 supports 60V, while that of IDA2030 (A) is 44V.

Different functions D1875: D1875 amplifier chip is designed for video circuit, mainly used in video circuit design applications. LM1875: The integrated circuit is equipped with overload overheating and sensitivityLoad reverse potential safe working protection.

lm1875: The output power is 20W. lm3886: Continuous output power 68W. Different sound quality characteristics lm1875: The sound quality is softer, less powerful than lm3886. lm3886: The distortion is small, the sound quality is more hierarchical and powerful.

Who has the internal circuit diagram of the 8051 chip?

This is my relative encoder circuit diagram. The absolute encoder I use is a magnetic encoding chip that reads the angles directlyAye.

is an 8-bit single-chip microcontroller of the MCS-51 single-chip class, manufactured by Intel Corporation in 1981.

The on-chip oscillator and clock generate the circuit, but the quartz crystal and trimmer capacitor need to be connected externally. The maximum allowable oscillation frequency is 12MHz. The maximum allowed oscillation frequency of SST89V58RD is 40MHz, which greatly improves the execution speed of instructions. These parts are connected to each other via an internal data bus.

MCU clock circuit is shown as follows: capacitor CC3 has a fine tuning effect on the frequency,Capacitor capacity selection range is 30pF±10pF. The selection of oscillation frequency ranges from 2-12MHz. Clock period = reciprocal of quartz oscillator frequency.
