Linear Technology's LT3012 and LT3013 micropower LDOs have low quiescent currents, making them suited to battery-powered applications.
Card power chip meets smart and SIM standards
The LTC4557 is a dual SIM/smart-card power supply and level translator, which provides both 1.8 and 3V SIM power and digital signal level shifting from a 3 x 3mm QFN package.
RF mixers take transformers onboard
Linear Technology has released two new high linearity up-converting RF active mixers with integrated RF transformers.
The wide adjustable output from 1.24 to 60V makes them ideal for automotive, 48V telecomms backup supplies and industrial control applications.
Additionally, their very low quiescent current as low as 40uA (operating) and 1uA (shutdown) make them an excellent choice for battery-powered memory "keep alive" systems that require extended run times.
The LT3013's power-good flag feature is programmable and indicates output regulation.
For high voltage applications that require large input/output differentials, the LT3012 and LT3013 offer a very compact and thermally effective solution.
The thermally enhanced DFN and TSSOP packages provide thermal resistances comparable to much larger conventional packages.
The LT3012 and LT3013 operate with very small, low cost ceramic output capacitors.
They are stable with only a 3.3uF output capacitor, compared with older regulator devices of comparable output current and high voltage requiring 10 to more than 100uF.
These tiny external capacitors can be used without any necessary series resistance as is common with many other regulators.
Internal protection circuitry includes reverse-battery protection, current limiting, thermal limiting, and reverse-current protection.
The LT3012EDE (12-lead low-profile 3 x 4mm x 0.75mm DFN package) and LT3012EFE (16-lead thermally enhanced TSSOP package) are available from stock.
1000-piece pricing is set at US $2.05 and $2.20 each, respectively.
The LT3013EDE and LT3013EFE are available from stock in the same packaging with 1000-piece pricing set at $2.25 and $2.40 each. Request a free brochure from Linear Technology Corp ...
