Dual-Output LDO Regulators Boast Low Ground Current

Four compact, dual-output, low-dropout (LDO) regulators are capable of converting inputs of 2.25V-5.5V to outputs as low as 1.5V at current levels of 150 mA and 300 mA. Claimed as operating with exceptional efficiency, the new devices provide a low ground current of just 48 µA. The SiP2210, SiP2211, SiP2213, and SiP2214 are available in a choice of two lead-free packages: a 3-mm by 3-mm MLP33-10 PowerPAK package with a fixed output or a MLP44-16 PowerPAK with an adjustable output. All four devices are capable of supplying 150 mA from output 1 and 300 mA from output 2. The SiP2210 and SiP2211 are pin-for-pin replacements for the MIC2210 and MIC2211 and are rated for a low dropout voltage of 65 mV at 100 mA and low ground current. Both feature independently enabled outputs, but the SiP2210 also includes an additional open-drain driver output capable of sinking 150 mA, as well as integrated POR (power-on reset) protection. The SiP2213 and SiP2214 are pin-for-pin replacements for the MIC2213 and MIC2214. In the SiP2213, the outputs are sequenced at power on, with output 1 settling before output 2 begins turning on. Both devices also feature an open-drain driver output capable of sinking 150 mA, as well as POR protection with an adjustable delay that can be set to alert the processor when the output of the regulator has reached and settled at its designated voltage. In addition, the devices offer extremely low noise of 30 µV with the addition of a bypass capacitor. Protection features include undervoltage lockout, output-current limiting and thermal shutdown. Samples and production quantities of the SiP2210/11/13/14 are available now. Pricing starts at $0.70/10,000. VISHAY INTERTECHNOLOGY INC., Malvern, PA. (619) 336-0860.
