TEXAS INSTRUMENTS -15V Fixed LDO Voltage Regulator, 1.5A, TO-220-3

The -15V Fixed LDO Voltage Regulator from TEXAS INSTRUMENTS is a 3-terminal negative device designed for reliable power management. It provides a stable -15V output with a maximum current of 1.5A, operating within an input voltage range of -35V to -17.5V.

Requiring only one external component—a compensation capacitor at the output—this regulator simplifies circuit design. It employs internal current limiting, safe area protection, and thermal shutdown, ensuring robust defence against virtually all overload conditions. The low ground pin current allows the output voltage to be easily boosted above the preset value using a resistor divider, while the low quiescent current drain ensures good regulation in the voltage boosted mode.

The device offers high ripple rejection and a 4% tolerance on the preset output voltage. Designed for through-hole mounting, it comes in a 3-pin TO-220 package with dimensions of 43 mm x 33 mm x 15 mm and a weight of 2.041 grams. It operates reliably in temperatures ranging from 0°C to 125°C. This green product contains no antimony or bromine, making it suitable for industrial and power management applications.
