(1)

All voltages are with respect to the GND pin.

(2)

Minimum and maximum limits are design targeted limits over the junction temperature (TJ) range of –40°C to +125°C, unless otherwise

stated. Typical values represent the most likely parametric norm at TJ = 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)

Dropout voltage is the voltage difference between the input and the output at which the FB voltage drops to 97% of its nominal value.

(5)

Short-circuit current (ISC) is equivalent to current limit. To minimize thermal effects during testing, ISC is measured with VOUT pulled to

100 mV below its nominal voltage.

(6)

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

IGND = ( (IIN – IOUT) + IEN + ILKG(PG))

(7)

Ground current in shutdown mode, IGND(SD), does NOT include current from PG pin.

(8)

This specification is verified by design.

6.5 Electrical Characteristics

VIN = VOUT(NOM) + 0.5 V or 1.3 V, whichever is greater; VEN = 1.2 V, CIN = 22 μF, COUT = 22 μF, OUT connected to 50 Ω to

GND, VFB = 0.5 V, CSS/NR = 0.12 µF, CFF = 0.01 µF, and PG pin pulled up to VIN by 100-kΩ resistor (unless otherwise

noted).
