ST’s LDH40 and LDQ40 voltage regulators ship as much as 200 mA and 250 mA, respectively, to be used in industrial and automotive functions. The LDH40 regulator offers an adjustable output voltage from 1.2 V to 22 V. Variants of the LDQ40 regulator supply both an adjustable output from 1.2 V to 12 V or a set output at 1.8 V, 2.5 V, 3.3 V, or 5.0 V. Output voltage tolerance is ±0.5% at 25°C and ±1.5% over temperature.
These two low-dropout (LDO) regulators begin up from an enter as little as 3.3 V and function with as much as 40 V utilized. To assist preserve battery power in always-on standby methods, the gadgets’ quiescent present is 2 µA at zero load and simply 300 nA in logic-controlled shutdown mode. Automotive variations are AEC-Q100 Grade 1 certified and function over a temperature vary of -40°C to +150°C.
The LDH40 automotive-grade regulator is in manufacturing now. Adjustable-output LDQ40 regulators, in industrial and automotive grades, are in manufacturing as effectively. Costs for each the LDH40 and LDQ40 automotive-grade components begin at $0.47 every in a number of 1000 items. Fastened-output LDQ40 automotive elements shall be out there in Q2, with industrial components to observe in Q3.
