LP5952 - Dual-Rail Linear Regulator

General Description

The LP5952 is a dual-supply-rail linear regulator optimized for powering ultralow-voltage circuits from a single Li-Ion cell or 3-cell NiMH/NiCd battery.

Key Features

  • 1 Input Voltage Range: 0.7 V to 4.5 V.
  • 2.5 V ≤ VBATT ≤ 5.5 V.
  • 0.5V ≤ VOUT ≤ 2 V.
  • Ensured 350-mA Output Current.
  • For ILOAD = 350 mA:.
  • VBATT ≥ VOUT(NOM) + 1.5 V or 2.5 V (Whichever is Higher).
  • For ILOAD = 150 mA:.
  • VBATT ≥ VOUT(NOM) + 1.3 V or 2.5 V (Whichever is Higher).
  • Excellent Load Transient Response: ±15 mV Typical.
  • Excellent Line Transient Response: ±1 mV Typical.
  • 50-µA Typical Quiescent Curren.
