1.5A, LOW QUIESCENT CURRENT, FAST TRANSIENT
ULTRA-LOW DROPOUT LINEAR REGULATOR
Electrical Characteristics
T_A = 25^oC, V_IN = 3.3V, V_OUT =1.8V, I_OUT = 10mA, V_EN = V_IN, C_IN = 10μF, C_OUT = 10μF, V_EN = 2V, unless otherwise stated.
Minimum and maximum limits are guaranteed through test, design, or statistical correlation. Typical values represent the most likely
parametric norm at T_A = 25^oC, and are provided for reference purposes only.

Notes:
4. Dropout voltage is the minimum voltage difference between the input and the output at which the output voltage drops 2% below its nominal value.
For any output voltage less than 2.5V, the minimum V_IN operating voltage is the limiting factor.
5. The line and load regulation specification contains only the typical number. However, the limits for line and load regulation are included in the adjust
voltage tolerance specification.
6. Device mounted on 2” x 2” FR-4 substrate PCB, 2oz copper with minimum recommended pad layout.
