(1)
Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings
only, which do not imply functional operation of the device at these or any other conditions beyond those indicated under Recommended
Operating Conditions. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
(2)
All voltages are with respect to the potential at the GND pin.
(3)
Minimum (MIN) and maximum (MAX) limits are specified by design, test, or statistical analysis. Typical numbers represent the most
likely norm.
(4)
VPOR is voltage at which the EPROM resets. This is different from the UVLO on VINLDO12, which is the voltage at which the
regulators shut off; and is also different from the nPOR function, which signals if the regulators are in a specified range.
(5)
Specified by design. Not production tested.
7.5 General Electrical Characteristics
Unless otherwise noted, VIN = 3.6 V. Values and limits apply for TJ = 25°C.

(1)

Minimum (MIN) and maximum (MAX) limits are specified by design, test, or statistical analysis. Typical (TYP) numbers represent the
most likely norm.
(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.
(5)
Pins 24, 19 can operate from VIN min of 1.74 V to a VIN max of 5.5 V. This rating is only for the series pass PMOS power FET. It allows
the system design to use a lower voltage rating if the input voltage comes from a buck output.
(6)
VIN minimum for line regulation values is 1.8 V.
(7)
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.
7.6 Low Dropout Regulators, LDO1 and LDO2
Unless otherwise noted, VIN = 3.6 V, CIN = 1 µF, COUT = 0.47 µF, and values and limits apply for TJ = 25°C, unless otherwise
specified.
