Overview

The HE2028 series is a high voltage, ultralow-power, low dropout voltage regulator. The device can deliver 800mA output current with a dropout voltage of 360mV and allows an input voltage as high as 50V. The typical quiescent current is only 2μA. The device is available in fixed output voltages of 3.3 and 5.0V. The device features integrated shortcircuit and thermal shutdown protection. Although designed primarily as fixed voltage regulators, the device can be used with external components to obtain variable voltages.

Applications

  • Portable, Battery Powered Equipment
  • Microcontroller Applications
  • Smoke detector and sensor
  • Audio/Video equipment
  • Weighting Scales
  • Home Automation

Key features

  • Good Transient Response
  • Output voltage accuracy: tolerance ±2%
  • SOT223-3L, and TO252-3L package PSRR: 85dB@1KHz
  • High input voltage (up to 50V)
  • Low Power Consumption: 2μA (Typ)
  • Maximum Output Current: 800mA
  • Voltage drop: 360mV@100mA(3.3V)
