Each LDO in the CAT6221 has an independent enable pin and, combined, offer low quiescent current, 1 percent initial accuracy, and a very low typical dropout voltage of 210mV at a 300mA load. Zero shutdown current, a low quiescent current of 100uA reduce power, and small, 1uF ceramic output capacitors provide stable operation, and minimize board space and component costs. Additional features include fold-back current limit and protection against short-circuit and thermal overload fault conditions.
CAT6221 LDO regulator is available in standard output voltage combinations of 2.8V/1.8V and 3.3V/1.8V. Additional output voltage combinations are available as special orders.
Product Features
-- Low drop out voltage of 210mV typical at 300mA
-- "Quick-start" feature for fast turn-on time (less than 150us)
-- Under-voltage lockout
-- No-load ground current: 100uA typical
-- +/- 1.0% output voltage initial accuracy, +/- 2.0% accuracy over temperature
-- Fold-back current limit and thermal protection
-- Packaging: 6-lead TSOT-23, 0.8mm height
Price and Availability
The CAT6221 LDO regulators are priced at $0.37 each in 10,000 piece quantities for the 2.8V/1.8V and 3.3V/1.8V standard output voltage combinations. Samples are available now. Projected lead-time for production quantities is currently 6 to 8 weeks ARO.
