The LR12K4-G from Microchip Technology is a high-voltage low dropout regulator delivering a fixed 88V output at up to 50mA. It offers 60dB PSRR at 120Hz, ensuring clean power for high-voltage analog circuits. The TO-252 (DPAK) package provides adequate thermal dissipation for this voltage range.
- High Output Voltage: 88V fixed output eliminates the need for series resistor dividers.
- Low Dropout Design: Efficient regulation even with input voltages close to 88V.
- Good Ripple Rejection: 60dB PSRR at 120Hz filters mains hum.
- Surface-Mount Package: TO-252 DPAK simplifies PCB assembly.
