Two regulators in one save space and
cost
Each LDO in the CAT6221 has an independent enable pin and, combined, offer low quiescent current, 1% initial accuracy, and a very low typical dropout voltage.
New from Catalyst Semiconductor, the CAT6221 integrates two 300mA regulators in a tiny 6-lead 0.8mm-high TSOT-23 package, providing a smaller cost-effective option for cellphones, battery-powered devices and other portable consumer products requiring two LDOs Each LDO in the CAT6221 has an independent enable pin and, combined, offer low quiescent current, 1% initial accuracy, and a very low typical dropout voltage of 210mV at a 300mA load

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.
Zero shutdown current, a low quiescent current of 100uA reduce power, and small 1uF ceramic output capacitors provide stable operation, and minimise board space and component costs.
Additional features include foldback current limit and protection against short-circuit and thermal overload fault conditions.
The CAT6221 LDO regulator is available in standard output voltage combinations of 2.8/1.8V and 3.3/1.8V.
Additional output voltage combinations are available as special orders.
The CAT6221 LDO regulators are priced at US $0.37 each in 10,000 piece quantities for the 2.8/1.8V and 3.3/1.8V standard output voltage combinations.
Samples are available now.
Projected lead-time for production quantities is currently 6 to 8 weeks ARO.
