The LM320T-15 is a fixed negative-output linear regulator delivering -15V at up to 1.5A. Packaged in TO-220-3, it features a low quiescent current of 2mA and PSRR of 64dB at 120Hz. This regulator is suitable for precision analog applications requiring a clean negative rail.
- High Output Current: 1.5A supports heavy analog loads.
- Low Quiescent Current: 2mA minimizes power loss.
- High PSRR: 64dB at 120Hz rejects ripple.
- TO-220-3 Package: Easy mounting and thermal management.
