This circuit can make DC voltage UV always stay at about 6.5V and has no reference to time and environmental temperature. Its main technical data: Steady output voltage: UN=6.5±5% V Output load current: IL=0~0.3mA Input voltage (supply voltage) : U1=19~54V Input current Ii (stable current Ia) : Ii＝Ia≈2mA Output resistor: dUN/dIN=r0=20Ω, maximum 50Ω Voltage-regulation coefficient: dUN/dUI=a=3×10-6, maximum 3×10-5 When the range of environmental temperature is 0~70℃, the average temperature coefficient of reference voltage: SAV=-100~+140μV/grd, typical value +67μV/grd Long term stability after working 100 hours: <1mV/1000 work hour Environmental temperature: θu=0~70℃
