Note 2: Line regulation (∆VOUT / (VOUT x ∆VIN)) and load regulation (∆VOUT/(VOUT x ∆IOUT)) are measured with pulses and do not include output voltage changes due to die-temperature changes. Note 3: Noise specifications are 100% tested for the 10Hz to 1kHz bandwidth. Contact factory for 100% noise testing in the 0.1Hz to 10Hz bandwidth. Note 4: Temperature hysteresis is specified at TA = +25°C by measuring VOUT before and after changing temperature by +25°C using the PDIP package. www.maximintegrated.com Maxim Integrated │ 5
