Dual-output LDOs drop in to boost
performance
Four compact dual-output low-dropout (LDO) regulators are capable of converting 2.25 to 5.5V inputs to outputs as low as 1.5V at current levels of 150 and 300mA.
Four compact dual-output low-dropout (LDO) regulators are capable of converting 2.25 to 5.5V inputs to outputs as low as 1.5V at current levels of 150 and 300mA Operating with exceptional efficiency, the new devices provide a low ground current of 48uA

Novel power package reduces MOSFET on-resistance
Siliconix has released 14 industry-leading PowerPAK power MOSFETs featuring improved package technology that yields lower on-resistance devices.
Drivers integrate MOSFETs with drive circuitry
Five new Little Foot Plus driver products are designed to simplify the use of N-channel MOSFETs in high-frequency buck regulators.
The new SiP2210, SiP2211, SiP2213 and SiP2214 LDO regulators are designed to provide space savings and enhanced electrical performance in portable electronic devices such as cellphones, PDAs, MP3 players and wireless modems.
Each part is available in a choice of two lead (Pb)-free packages: a very small 3 x 3mm MLP33-10 PowerPAK package with a fixed output or a MLP44-16 PowerPAK package with an adjustable output.
All four devices are capable of supplying 150mA from output 1 and 300mA 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 65mV at 100mA and low ground current.
Both feature independently enabled outputs, and the SiP2210 also includes an additional open-drain driver output capable of sinking 150mA, 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 150mA, 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 to low dropout values and low power consumption, the new devices offer extremely low noise of 30uV 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, with lead times of seven to eight weeks for larger orders.
Pricing for US delivery starts at $0.70 in 10,000-piece quantities.
