LDOs are frugal for power-sensitive
systems
Two micropower low dropout (LDO) regulators for standby applications in portable and fixed power-sensitive systems are now available from Micrel.
Two micropower low dropout (LDO) regulators for standby applications in portable and fixed power-sensitive systems are now available from Micrel Consuming only 18uA of quiescent current, the MIC5233 is capable of supplying up to 100mA of output current, and the MIC5235 is capable of supplying 150mA

World's simplest buck regulator boosted to 2A
Micrel has boosted the output capability of the industry's simplest surface-mount DC/DC switching convertor to 2A while retaining the device's original SO-8 packaging.
Dual and triple 135MHz low-power op amps
Consuming just 2.4mA per op amp, the MIC915 dual and MIC916 triple op amps extend Micrel's premier family of high-speed, low-power op amps for power-sensitive high-speed applications.
The MIC5233 supports an input voltage range of 2.3 to 36V, and the MIC5235 supports a range of 2.3 to 24V.
Both devices are new additions to Micrel's line of IttyBitty SOT-23-5 LDO regulators featuring uCap capability which allows a choice of either ceramic or tantalum capacitors.
"The MIC5233 and MIC5235 are not limited to battery operated applications", said John McGinty, senior product marketing engineer, at Micrel.
"The unique combination of high input supply and low quiescent current allows them to fit into a wide range of portable and fixed applications for providing a stand-by supply voltage".
"For example, the MIC5233 is suitable for keep-alive circuitry in four-cell lithium-ion (Li-ion) battery applications where the input voltage can be as high as 30V or in fixed telecomms systems that require low voltage bias supplies from a high voltage input", McGinty said.
"Similarly, the MIC5235 is suitable for keep-alive circuitry in three-cell Li-ion battery applications where input voltages can be as high as 24V - or in a PDA where the input can be a one-cell Li-ion battery".
When the devices are purchased in a quantity of 1000, pricing starts at $1.00 for the MIC5233, and $0.84 for the MIC5235.
Samples are available, and production quantities are stock to 8 weeks ARO.
