524 1V-LDO

524 : 1V-LDO

Design render

How it works

Just a low-drop out regulator that takes in 1.2V-3V on an analog pin and outputs 1V through another analog pin.

schematic

layout

ttlayout

Its expected characteristics are:

  • output voltage: 1V
  • dropout voltage: 0.2V
  • maximum output current: 50mA
  • efficiency: 82% @Vin=1.2V, 55% @Vin=1.8V
  • max Vin: 4V
  • line regulation: 6.78mV/V
  • load regulation: 67mV/A

How to test

Connect Vin to your input voltage and Vref to 0.6V, Vout is the output voltage

External hardware

List external hardware used in your project (e.g. PMOD, LED display, etc), if any
