Positive Voltage Regulator 7812 12V 1.5A TO-220

Description

7812 Positive Voltage Regulator 12V 1.5A TO-220 The 7812 Positive Voltage Regulator 12V 1.5A TO-220 is a three-terminal fixed +12V linear regulator supplied in a TO-220 through-hole package, designed to provide local on-card regulation with up to 1.5A output current and built-in protections including thermal shutdown, current limiting and safe-area protection for robust and reliable operation in consumer, industrial and embedded power systems. 7812 is part of a series of 78XX voltage regulators. For ICs within the family, the xx is replaced with two digits, indicating the output voltage (for example, the 7805 has a 5-volt output, while the 7812 produces 12 volts). Features Output current capability up to 1.5A with internal current limiting and thermal shutdown. Safe Operating Area (SOA) protection for reliable operation under varying load and pulse conditions. Low dropout characteristic of approximately 2.0V at 1.0A for moderate headroom designs. Low quiescent supply current in the single-digit milliampere range for efficient operation. Excellent supply-rejection performance and low output noise suitable for analog circuits. Minimum load requirement of 5mA to maintain regulation. Standard TO-220 mounting for easy heatsinking and replacement.
