High Temperature Linear Regulator With Low Output Noise

Voltage regulator-LHVR230/LHVR230H LHVR230/LHVR230H series circuit is a precision voltage positive stabilized power supply module especially designed for operations under high temperature and wide range temperature environment,Website:http://www.drillingpartss.com, 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 230℃. The devices can be widely used in oil well logging, programmable power supply and other harsh environments.Product characteristics: Output current: 1.5AInput voltage: 40VWorking temperature: -55℃～+250℃Storage temperature: -65℃～＋250℃Power: LHVR230/250-15W；LHVR230H/250H -30WParameters Test conditions Test temperature Typical values Parameters Input voltageVin1Vin2Vin1Vin2Input DC voltage while testing8V（Vo2+4）V（Vo1-4）V（Vo2+4）VThe minimum input DC voltage+7.5V（Vo2+2.5）V（Vo1-3）V（Vo2+3）VLoad current1AOutput voltage accuracy±1%Output noise≤1mVVoltage regulation rate（Vin=VT~30V） ±2%±0.5%Current load regulation rate±2%±1%Output voltage temperature shift(Tc=230℃)±120ppmProduct models:Parameters Test conditions Test temperature Typical values Parameters Input voltageVin1Vin2Vin1Vin2Input DC voltage while testing8V（Vo2+4）V（Vo1-4）V（Vo2+4）VThe minimum input DC voltage+7.5V（Vo2+2.5）V（Vo1-3）V（Vo2+3）VLoad current1AOutput voltage accuracy±1%Output noise≤1mVVoltage regulation rate（Vin=VT~30V） ±2%±0.5%Current load regulation rate±2%±1%Output voltage temperature shift(Tc=230℃)±120ppmDimensions and lead arrangement Note :All kinds of high temperature resistant positive voltage regulators with different output voltage can be customized according customers’ requirements.Purchase details:  Payment Term:   T/T, West Union, Paypal, MoneyGram (Any way convenient for you, get contact with us)      Warranty  All devices’ performance will be tested qualified before shipping  30 days guarantee of quality (after our delivery date).According to contract and technical agreement requirements, within warranty period, we promise to refund or exchange the devices with quality problem which caused by our side;Beyond warranty period, we promise to do our best offer technical guidance help customer solve problems.Refund &ReplacementThe Marketing Department is responsible for carrying out of the refund & replacement process;The Technical Department takes responsibility for testing the quality of problem products;Inventory Keeper takes charge of receiving and exchanging of the replaced products.Range: Quality problem;  Packaging problems;  Other problems caused by our side result in products impossible to use or sell.       (All the problems should be tested by our Technical Department)Shipping  Through EMS, FEDEX, UPS, TNT, DHL.
