Tiny LDO is a speedy turn-on
Low dropout regulator provides a 500mA peak output current in a tiny five-lead 1mm-profile thin SOT-23 package.
Catalyst Semiconductor has launched the first device in its new line of low dropout (LDO) regulators The CAT6219 LDO regulator is one of only a few devices available that provides a 500mA peak output current in a tiny five-lead 1mm-profile thin SOT-23 package

Digitally programmable potentiometers to take over
Catalyst Semiconductor has added two new digitally programmable potentiometer (DPP) ICs to its AE2 (analogue EEPROM) mixed-signal product line.
An alternative to Micrel's MIC5219 and MIC5319 LDO regulators, the CAT6219 offers a lower quiescent current combined with a low typical dropout voltage of 300mV at a 500mA load.
Additionally, an external bypass capacitor reduces overall output noise making the device ideal for low noise applications.
Many LDOs incorporating a bypass capacitor pay the penalty of slow "startup".
However, Catalyst's device is designed with a "quick start" feature, which ensures a fast turn-on time of less than 150us and further optimises the CAT6219 for low-power applications.
The CAT6219 is designed to eliminate battery drain when not in use by entering a "zero" current shutdown mode.
Additionally, the device offers a low typical quiescent current of 55uA and protection against short-circuit and thermal overload fault conditions.
The CAT6219 low dropout regulator is priced at US $0.28 each in 10,000 piece quantities.
Samples are available now.
Projected lead-time for production quantities is currently 6 to 8 weeks ARO.
