L7805CV Voltage Regulator: Features, Pinout, Datasheet and Spot Price
L7805CV Description:
The L7805CV is a popular fixed output voltage regulator used to convert an unstable input voltage into a regulated 5V DC output voltage. Usually users also call it l7805cv transistor, ic l7805cv and so on.
Linear regulators are just buck regulators. There are two types of voltage regulators: shunt regulators and series regulators.
For IC linear regulators, the regulator type determines the pass device configuration as well as the dropout voltage. Standard regulators use an NPN Darlington configuration with a dropout voltage between 1.5V and 2.2V. Low dropout (LDO) regulators differ from standard regulators in that the pass device consists of a single PNP transistor
Linear regulators offer significant advantages over switching regulators in terms of simplicity, cost, and output noise.
The only difference between a "normal" linear regulator and an LDO regulator is the lower constant voltage drop across the series pass element of the LDO type.
The L78xx series of three-terminal positive voltage regulators are available in TO-220, TO-220FP, TO-3, D 2 PAK and DPAK packages and a variety of fixed output voltages,
making them suitable for a wide range of applications, the series of models include:
L7805CV , L7805CV-DG , L7805ABD2T , L7805ABP , L7805ABV , L7805T , L7806ABD2T , L7806ABV , L7806ACD2T-TR ,
L7808ABF , L7808ACV-DG , L7809ABV , L7809CD2T-TR , L7809CF , L7810CV , L7812ABV-DG , L7824CT , L78L05ABD , L78L09ACD , L78L12ABD-TR .. etc
It is worth noting that this series is officially sold in jinftry, and the price advantage is obvious, for example: L7805CV price is between $0.4--$0.59, welcome to consult.
These regulators provide local on-card regulation, eliminating allocation problems associated with single-point regulation. Each type employs internal current limiting, thermal shutdown, and safe-area protection, making them essentially indestructible. They can deliver more than 1 A of output current if adequate cooling is provided. Although primarily designed as fixed voltage regulators, these devices can be used with external components for adjustable voltage and current.
ST Micro L7805ACV is a 5V positive linear regulator. It has 1 amperage, 4% tolerance, commercial temperature, and comes in a TO-220 package.
The following are the main application functions, features and some alternative models of ic l7805cv
L7805 Voltage Regulator
ic l7805cv application function:
Fixed output voltage regulation, the output is 5V.
It can be used in a variety of electronic products and applications, such as home appliances, power adapters, industrial equipment, etc.
Provides a stable power supply for various circuits.
working principle:
Input Voltage: The L7805CV generally accepts an input voltage between 7V and 35V (recommended minimum input voltage is 7.5V to ensure a stable 5V output), but this range may vary between different manufacturers.
Internal reference voltage: L7805CV has a fixed reference voltage source inside. By comparing this reference voltage to the regulated output voltage, the regulator adjusts its internal resistance to ensure that the output voltage remains at 5V.
Internal Feedback: The regulator utilizes a feedback mechanism to regulate the output voltage. When the output voltage rises, the regulator increases its internal resistance, causing the output voltage to decrease; when the output voltage falls, it decreases its internal resistance, causing the output voltage to increase.
Protection functions: Most of the L7805CV regulators have thermal protection and short circuit protection functions. These features prevent device damage under extreme conditions. For example, when the internal temperature of the device is too high, the overheating protection will automatically disconnect the output to prevent damage to the device.
L7805CV transistor features:
The output voltage is 5V.
The maximum output current is typically 1.5A.
