The Texas Instruments LM320T-15/NOPB is a fixed -15V negative linear voltage regulator capable of delivering 1.5A. It features a quiescent current of 2 mA and a PSRR of 64dB at 120Hz. The TO-220-3 package provides excellent thermal performance and is ideal for through-hole PCB designs. This regulator is a reliable choice for high-current negative supply applications in industrial, audio, and telecommunications systems.
- High Output Current (1.5A): Supports demanding loads that require more current than typical LDOs.
- Fixed -15V Output: Provides a precise negative rail without external adjustment components.
- High PSRR (64dB @ 120Hz): Ensures clean output by rejecting input ripple and noise.
- TO-220 Package: Excellent thermal dissipation for continuous high-current operation with a heatsink.
