LDO Family Adds SOT-23 Siblings

Two additions to the company's low dropout (LDO) regulator line are the CAT6217 and CAT6218 LDO regulators that source 150 mA and 300 mA, respectively, in 5-lead, 1-mm profile SOT-23 packages. Typical dropout voltage is 90 mV at a 150 mA load for the CAT6217 and 180 mV at a 300 mA load for the CAT6218. Both devices eliminate battery drain when not in use by entering a zero-current shutdown mode. They also specify a typical quiescent current of 55 µA and include protection against short-circuit and thermal-overload fault conditions. The CAT6217 is available in output voltages of 1.5V, 1.8V, 2.5V, 2.8V, 2.85V, and 3.3V, while the CAT6218 offers output voltages of 1.8V, 2.4V, 2.7V, 2.85V, 3.0V, 3.2V, and 3.3V. Prices for the CAT6217 and CAT6218 are $0.20 and $0.23 each/10,000, respectively. CATALYST SEMICONDUCTOR INC., Sunnyvale, CA. (800) 258-5991.
