Low dropout regulators for emerging 42 V automotive market
27 March 2002, Power Electronics / Power Management

National Semiconductor's latest additions to its low dropout (LDO) family of regulators are aimed at automotive applications. The LM2936HV meets the stringent demands of the automotive industry and supports the new 42 V standard now being adopted by automakers. The 42 V standard will enable carmakers to replace mechanical and hydraulic systems with electrical systems to create cars that are lighter, more reliable, and produce fewer emissions. For example, some of these systems are: integrated starter/alternators, electronic 'drive-by-wire' steering, advanced braking, and other cutting-edge technologies set to begin hitting the market in 2005.

The LM2936HV ultra-low quiescent current regulator features low dropout voltage and low current in the standby mode. The device supports continuous input voltages up to 60 V with a 50 mA output. It features an ultra-low quiescent current (9 µA, typical) -ideal for sleep mode and other 'keep alive' applications. The LM2936HV is offered in small outline (SOIC) package and a 5 V output. Variations of the product at 3 and 3,3 V will be available shortly.
