Ultra-Low Output Voltage, Low-Quiescent-Current Linear Regulator for High-Temperature Applications

Maxim Integrated 

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 1)

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.
