DESCRIPTION
The chips are available in a standard 8-lead SOP-8 package. Other feature include a guaranteed ̈́4% to tolerance on output voltage under specified input voltages and output load conditions. The 150 kHz ̈́15% is on the oscillator frequency. External shutdown is included, featuring 80uA (Typ.) standby current. The output switch includes cycle-by cycle current limiting, as well as thermal shutdown for full protection under fault conditions. FEATURES
