LM2674 Datasheet, National Semiconductor

include a guaranteed ± 1.5% tolerance on output voltage within specified input voltages and output load conditions, and ± 10% on the oscillator frequency. External shutdo.

n Simple High Efficiency ( > 90%) Step-Down (Buck) Regulator n Efficient Pre-Regulator for Linear Regulators n Positive-.

The LM2674 series of regulators are monolithic integrated circuits built with a LMDMOS process. These regulators provide all the active functions for a step-down (buck) switching regulator, capable of driving a 500 mA load current with excellent line.
