  • 3.3V, 250mA positive fixed voltage regulator
  • 0.4V dropout at 250mA
  • Only requires a single 2.2µF capacitor between Vout and GND (but a 0.1µF on input is a good idea)
  • Pin assignments (viewed pins down; flat face toward you): 1 = Vout, 2 = GND, 3 = Vin
  • TO92 through-hole transistor-like package
