MAX16999
Ultra-Low Output Voltage, Low-Quiescent-Current
Linear Regulator for High-Temperature Applications
Typical Operating Characteristics
(For devices with VOUT < 1.5V, VIN = 3.3V. For devices with VOUT > 1.5V, VIN = 5V. EN = IN, CIN = 1μF, COUT = 4.7μF, CCRES = 1000pF,
TA = + 25°C, unless otherwise noted.)
