Catalyst Semi Rolls Out Dual, 300mA LDO Regulator
Catalyst Semiconductor, Inc. introduced its newest low dropout (LDO) regulator – the CAT6221 300mA, dual-output LDO. Announced just weeks after its CAT6217 and CAT6218 single-output LDO regulators, the CAT6221 integrates two 300mA regulators in a tiny, 6-lead, 0.8mm height TSOT-23 package, providing what is described as a smaller, cost-effective option for cell phones, 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. 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. 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 $0.37 each in 10,000 piece quantities for the 2.8/1.8V and 3.3/1.8V standard output voltage combinations. Projected lead-time for production quantities is currently 6 to 8 weeks ARO.
