A buried-zener reference core provides inherently low noise and excellent long-term stability. A chopper-stabilized amplifier buffers the reference and drives the 3.3V output. The series architecture allows the output to be loaded up to \u00b15 mA without degradation. ENABLE pin provides power-down capability reducing IQ to <1 \u00b5A.<\/p>\n
