JIANGSU CHANGJING ELECTRONICS TECHNOLOGY CO., LTD. 500mA Three Terminal Positive Voltage Regulators CJ78M Series 1 Three Terminal Positive Voltage Regulators Introduction The CJ78M series is a group of three terminal positive voltage linear regulators with multiple fixed output voltages. In the case of good heat dissipation, it can provide an output current of 500mA, and has internal short-circuit protection and thermal shutdown protection, which makes it not affected by overload. In addition to being used as fixed voltage regulators, these devices can also be used with external components to obtain adjustable output voltage and current, and can also be used as power transmission elements in precision regulators. 2 3 Features • Output Current: up to 500mA at TJ = 25°C • Available Output Fixed Voltage: 5.0V, 6.0V, 8.0V, 9.0V and 12V Output Voltage Tolerance: ±3% at TJ = 25°C ±5% over the Operating TJ • • Line Regulation: 3.0 ~ 10mV (Typ.) at TJ = 25°C • Load Regulation: 15 ~ 25mV (Typ.) at TJ = 25°C • • Dropout Voltage: 2.0V@350mA Power Supply Rejection Ratio: 80dB@120Hz (Typ.) Operating Junction Temperature: -40 ~ 125°C Built-in Current Limit Short Circuit Protection Thermal Shutdown Protection 4 Applications • Appliances and White Goods Building Automation Computing & Servers Electronic Point-of-sale Motor Drives On-Card Regulation Portable Devices Telecommunications TVs and Set-top Boxes • Available Packages • PART NUMBER PACKAGES • TO-220-3L • TO-251-3L CJ78M Series TO-251S TO-252-2L • • • VIN 1 CJ78M Series 3 VOUT • • • CIN 2 0.33μF COUT • 0.1μF • Fixed Output Voltage Regulator Please carefully read the notice at the end of this data sheet about product use, data sheet changes and important statements.
