LP5912 Ultra-Low-Noise LDOs

Texas Instruments offers its LP5912 500 mA, ultra-low-noise LDOs for RF and analog circuits

Image of Texas Instruments' LP5912 Ultra-Low-Noise LDOsTexas Instruments' LP5912 are LDOs capable of supplying 500 mA output current. Designed to meet the requirements of RF and analog circuits, the LP5912 devices provide low noise, high PSRR, low quiescent current, and low line and load transient response. The LP5912 offer class-leading noise performance without a noise-bypass capacitor and with the ability for remote output capacitance placement.

The devices are designed to work with a 1 µF input and a 1 µF output ceramic capacitor (no separate noise-bypass capacitor required). These devices are available with fixed output voltages from 0.8 V to 5.5 V in 25 mV steps.

Features  
  • Input voltage range: 1.6 V to 6.5 V
  • Output voltage range: 0.8 V to 5.5 V
  • Output current up to 500 mA
  • Low output voltage noise: 12 µVRMS typical
  • PSRR at 1 kHz: 75 dB typical
  • Output voltage tolerance (VOUT ≥ 3.3 V): ±2%
  • Low IQ (enabled, no load): 30 µA typical
  • Low dropout (VOUT ≥ 3.3 V): 95 mV typical at 500 mA load
  • Stable with 1 µF ceramic input and output capacitors
  • Thermal-overload and short-circuit protection
  • Reverse-current protection
  • No noise-bypass capacitor required
  • Output automatic discharge for fast turnoff
  • Power-good output with 140 µs typical delay
  • Internal soft-start to limit the in-rush current
  • -40°C to 125°C operating junction temperature range
