LDOs boast low Iq
15 October 2008
Power Electronics / Power Management
ON Semiconductor has expanded its portfolio of low dropout (LDO) linear voltage regulators for automotive electronics modules that require very low ignition-off currents. Qualified to AEC-Q100 and operating across a wide temperature range, the new NCV86xx LDOs combine high levels of onboard functionality with typical quiescent currents (Iq) as low as 22 μA.
Delivering precision output voltages of 3,3 V and 5,0 V and output currents up to 350 mA, the battery-connectable family features onboard protection functions and include devices with power-on reset and delay time select capabilities. The LDOs are ideal for automotive system power modules that need to meet stringent criteria for current use while vehicle ignition is turned off. By using the LDOs to minimise quiescent current in the regulation portion of the module, designers can allocate more current to higher level design elements including microprocessors and CAN and LIN network components.
The new NCV8660 and NCV8665 families are available with output current capability of 150 mA. Devices in both families offer power-on reset and delay time select functionality. Typical quiescent currents are 28 μA and 30 μA respectively. Also offering output current of 150 mA is a new version of the NCV8664. This device has a typical Iq of just 22 μA and can provide a regulated output voltage of either 3,3 V or 5,0 V in designs where integrated power-on reset is not required.
For applications demanding output currents up to 350 mA, the new NCV8674 and NCV8675 families are both available with 3,3 V and 5,0 V output options and have respective typical quiescent currents of 27 μA and 34 μA. The NCV8675 incorporates power-on reset functionality and is available with a choice of reset delay times.
All of the new devices operate with output voltage accuracy of ±2,0% and incorporate short circuit and thermal overload protection, while the NCV8660 offers internal short circuit and thermal shutdown functions. These LDOs can sustain input voltage transients inherent to direct battery connection, eliminating the need for intermediate conversion or protection devices.
