ELECTRICAL CHARACTERISTICS (continued)
(VIN = 15V, SHDN = VIN, ILOAD = 5µA, TA = TMIN to TMAX, unless otherwise noted. Typical values are at TA = +25°C.) (Note 2)

Note 2: Limits are 100% production tested at TA = +25°C. Limits over the operating temperature range are guaranteed through
correlation using standard quality-control (SQC) methods.
Note 3: Pulse tested at VIN = 28V, ILOAD = 30mA to avoid exceeding package power-dissipation limits.
Note 4: Guaranteed by design. Tested with VOUT set to 5V. Dropout voltage is tested by reducing the input voltage until VOUT drops
to 100mV below its nominal value, measured with VIN starting 2V above VOUT.
Note 5: Use at least 1µF minimum for light loads. Add 0.125µF/mA (0.2µF/mA for the MAX1616) for loads greater than 100µA,
not production tested. See Capacitor Selection in the Applications Information section.
