250mA Ultra-Low-Noise Low-IQ LDO - LP5907
 

Recommended alternative parts

  • TPS7A92  -  TPS7A92 is a lower noise (4.6 µVRMS), 2A LDO in a small package (6.25 mm2)
  • TPS7A83A  -  TPS7A83A is an improved noise (4.4μVRMS), higher accuracy (0.75%), 2A LDO

Description

The LP5907 is a low-noise LDO that can supply up to 250 mA output current. Designed to meet the requirements of RF and analog circuits, the LP5907 device provides low noise, high PSRR, low quiescent current, and low line or load transient response figures. Using new innovative design techniques, the LP5907 offers class-leading noise performance without a noise bypass capacitor and the ability for remote output capacitor placement.

The device is designed to work with a 1-µF input and a 1-µF output ceramic capacitor (no separate noise bypass capacitor is required).

This device is available with fixed output voltages from 1.2 V to 4.5 V in 25-mV steps. Contact Texas Instruments Sales for specific voltage option needs.

Features

  • Input Voltage Range: 2.2 V to 5.5 V
  • Output Voltage Range: 1.2 V to 4.5 V
  • Stable With 1-µF Ceramic Input and Output Capacitors
  • No Noise Bypass Capacitor Required
  • Remote Output Capacitor Placement
  • Thermal-Overload and Short-Circuit Protection
  • –40°C to 125°C Operating Junction Temperature
  • Low Output Voltage Noise: < 6.5 µVRMS
  • PSRR: 82 dB at 1 kHz
  • Output Voltage Tolerance: ±2%
  • Very Low IQ (Enabled): 12 µA
  • Low Dropout: 120 mV (typical)
