Dual Channel Voltage Regulator
Product introduction
LH42094 series circuit is a precision voltage positive stabilized power supply module especially designed for operations under high temperature and wide range temperature environment,Website:, this voltage regulator has the characteristics that output doesn’t change as the input voltage, load current and environment temperature. Without connection with the external filter capacitance, the output noise is less than 1mV, and can operate reliably for long term period under shell temperature of 200℃. The voltage regulation rate and positive load rate are smaller compared with the same models abroad.Technical Parameters Output current: 1.5AInput voltage: 40VWorking temperature: -55℃～+250℃Storage temperature: -65℃～＋250℃Power: LH42117/8-8W；LH42094/5-20WParameters Test conditions Test temperature Typical values Output voltageIout=300mA,Vin=Vout+4VDC-4VDC +25℃ Vout±1%Output voltage temperature coefficientIout=300mA,Vin=Vout+4VDC +25℃～+200℃ ±50ppm（Vout≥3.3V） ±120ppm（Vout＜3.3V） Voltage input regulation rateVin=Vout+4VDC~40VDC Iout=50mA+25℃～+200℃ Vout±0.5%（Vout≥3.3V） Vout±2%（Vout＜3.3V） Current positive load regulation rateVin=Vout+5VDC Iout=50mA～300mA+25℃～+200℃ Vout±0.5%（Vout≥3.3V） Vout±1%（Vout＜3.3V） Wave attenuation （120Hz） Vin=Vout+5VDC +25℃ -60dBStatic currentVin=Vout+5VDC, Iout=0+25℃ 30mAShort circuit currentVin=Vout+5VDC +25℃ 400mAShort circuit currentVin=Vout+5VDC +200℃ 200mAKnee currentVin=Vout+5VDC +25℃ 2AKnee currentVin=Vout+5VDC +200℃ 2AOutput noiseVin=Vout+5VDC ,Iout=300mA+25℃ 1mVRMS The minimum differential voltage ( ΔV= VIN – VOUT )Iout=300mA+25℃～+200℃ 4VDCProduct models:Models Output voltage (V) The maximum output current(A) Typical current of knee current(A) LH42094-1.81.81.52LH42094-2.52.51.52LH42094-3.33.31.52LH42094-551.52LH42094-991.52LH.52LH.52LH.52Dimensions and lead arrangement Leading-out terminal Signal and note 1Ground2Output voltageShellInput voltage LH42117 series circuit is a precision voltage negative stabilized power supply module especially designed for operations under high temperature and wide range temperature environment, this voltage regulator has the characteristics that output doesn’t change as the input voltage, load current and environment temperature.
