MAX16999
Ultra-Low Output Voltage, Low-Quiescent-Current
Linear Regulator for High-Temperature Applications
DC Electrical Characteristics (continued)
(For devices with VOUT ≤ 1.5V, VIN = 3.3V. For devices with VOUT > 1.5V, VIN = 5V. EN = IN, TJ = -40°C to +125°C, CIN = 1μF, COUT
= 4.7μF, CCRES = 1000pF, 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 by design.
Note 3: Dropout voltage is defined as VIN - VOUT when VOUT is 2% below its value for VIN = VOUT + 2V.
