The LM79L05TA is a fixed negative linear regulator providing -5V at up to 100mA. Packaged in TO-92-3, it features a dropout voltage of 1.7V at 40mA and a quiescent current of 6mA. With 49dB PSRR at 120Hz, it delivers clean power for sensitive analog applications, making it a reliable choice for negative rail generation.
- High PSRR: 49dB at 120Hz effectively filters ripple, ideal for audio.
- Low Dropout: 1.7V at 40mA allows efficient operation.
- Small Package: TO-92-3 saves board space.
- Low Quiescent Current: 6mA minimizes standby power.
