The LP2989AIMM-3.0/NOPB is a 500mA low-dropout regulator with a fixed 3.0V output. Featuring 60dB PSRR at 1kHz and a dropout of 0.65V at full load, it delivers clean, stable power for noise-sensitive analog and RF circuits. The 8-VSSOP package is ideal for compact portable designs.
- Excellent Noise Rejection: 60dB PSRR at 1kHz filters high-frequency interference.
- Reliable 500mA Output: Supports moderate-load applications with stable 3.0V.
- Compact 8-VSSOP: Saves PCB area for space-limited designs.
- Low Dropout: 0.65V at 500mA enables efficient 3.65V to 3.0V conversion.
RF Transceiver Power Supplies
60dB PSRR at 1kHz suppresses noise from switching regulators, ensuring clean 3.0V for GSM/WiFi modules.
Audio Codec Supply
Low noise and 500mA capability power audio codecs in portable players, maintaining signal integrity.
