(1)

All voltages are with respect to the device GND pin.

(2)

Minimum and maximum limits are ensured through test, design, or statistical correlation over the TJ range of –40°C to 125°C, unless

otherwise stated. Typical values represent the most likely parametric norm at TA = 25°C, and are provided for reference purposes only.

(3)

CIN, COUT: Low-ESR Surface-Mount-Ceramic Capacitors (MLCCs) used in setting electrical characteristics.

(4)

The device maintains a stable, regulated output voltage without a load current.

(5)

Quiescent current is defined here as the difference in current between the input voltage source and the load at VOUT. IQ = (IIN – IOUT)

(6)

Output reverse current (IRO) is measured at the IN pin.

(7)

Ground current is defined here as the total current flowing to ground as a result of all input voltages applied to the device.

(8)

Dropout voltage is the voltage difference between the input and the output at which the output voltage drops to 100 mV below its

nominal value. Dropout voltage is not a valid condition for output voltages less than 1.3 V as compliance with the minimum operating

input voltage can not be ensured.

(9)

This specification is verified by design.

6.5 Electrical Characteristics

Unless otherwise specified, VIN = VOUT(NOM) + 0.5 V, VEN = 1 V, IOUT = 1 mA, CIN = 1 µF, COUT = 1 µF.
