Voltage Regulators Allow Large Transient Range
With an input voltage range from 4.5 V to 42 V, SIMPLE SWITCHER step-down voltage regulators from National Semiconductor allow for voltage transients from 12 V and 24 V input rails. The regulators feature internal compensation and low pin-count packages. The 11 SIMPLE SWITCHER step-down voltage regulators support load currents from 0.5 A to 5 A. Each provides a fixed switching frequency at 500 kHz and adjustable switching frequency or frequency synchronization up to 1 MHz, which allows for electromagnetic interference (EMI) reduction in noise-sensitive automotive, industrial, and communication applications. The 11 step-down voltage regulators range in price from $1.30 to $3.25 in 1,000-unit quantities.
