LP5912-3.3DRVR TI Voltage Regulators - Linear, Low Drop Out (LDO)

The LP5912 is a 500-mA low-noise LDO with fixed 3.3-V output, operating from a 2.5-V to 6.5-V input. It features ultra-low output noise of 6.5 μVRMS and high PSRR of 90 dB at 1 kHz, making it ideal for RF powering. Quiescent current is 20 μA typical with 1 μA in shutdown. Dropout voltage is 80 mV typical at 250 mA and 160 mV at 500 mA. Output accuracy is ±2% over temperature. The device includes enable and power-good output for supply sequencing. Packaged in a 6-pin WSON (DRV) (2 mm × 2 mm), the LP5912 is optimal for noise-sensitive analog circuits. Applications include RF power supplies for WiFi and Bluetooth chips, audio codec power, low-noise sensor supplies, and power for high-performance ADCs.
