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.
The low input voltage capability is important, as many emerging handheld applications are using a 1.5V main bus rail, and require output voltages from 1.25 to 0.5V to drive low voltage microprocessor and microcontroller cores.
The LTC3025 can also be used for 3.3/5V down to 1.20V output voltage as it has a 0.4V reference.
In addition, the LTC3025 offers micropower operation with only 54uA of quiescent current, and less than 1uA in shutdown, maximising run time in handheld applications.
The LTC3025 regulator optimises stability and transient response with low ESR ceramic output capacitors as small as 1uF.
Other LTC3025 features include +/-2% voltage accuracy over temperature and supply load, fast transient recovery, current limiting and thermal overload shutdown.
Its shutdown disconnect feature disconnects both input and bias voltages from the output in shutdown mode.
The LTC3025 regulator is available in a low profile 6-lead DFN (2 x 2 x 0.75mm) package with an exposed pad, offering a very compact and thermally efficient solution.
The LTC3025 is packaged in a 2 x 2mm QFN-6 and is available from stock.
Pricing starts at $1.65 each for 1000-piece quantities. Request a free brochure from Linear Technology Corp ...
