Overview

The LD39050 provides 500 mA current with an input voltage range from 1.5 V to 5.5 V and a typical dropout voltage of 200 mV. Stability is given by ceramic capacitors. The ultra low dropout voltage, low quiescent current and low noise features make it suitable for low power battery-powered applications. Power supply rejection is 65 dB at low frequencies and starts to roll off at kHz. The enable logic control function puts the LD39050 in shutdown mode allowing a total current consumption lower than 1 µA. The device also includes short-circuit constant current limiting and thermal protection.

Key features

  • Ultra low-dropout voltage (200 mV typ. at 50 mA)
  • Very low quiescent current: 100 μA typ. at 500 mA load, 1 μA max (shutdown)
  • Output voltage tolerance: ±2.0% @ 25 °C, 500 mA
  • Adjustable output voltage from 0.8 V up to input voltage
  • Compatible with (3x3 mm) and (2x2 mm) ceramic capacitors
  • Operating temperature range: -40 °C to 125 °C
