(1)

All voltages are with respect to the potential at the GND pin.

(2)

Minimum and Maximum limits are specified by design, test, or statistical analysis. Typical numbers are not ensured, but do represent the

most likely norm.

(3)

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

(4)

Quiescent current is defined here as the difference in current between the input voltage source and the load at the OUT pin.

(5)

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

(6)

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. This parameter only applies to output voltages above 2.5 V.

(7)

Short-circuit current is measured with OUT pulled to 0 V and IN worst case = 6 V.

(8)

This specification is specified by design.

(9)

There is a 1-M

Ω resistor between EN pin and ground on the device.

6.5 Electrical Characteristics

Unless otherwise noted, specifications apply in Figure 16 with: VIN = VOUT (NOM) + 1 V, VEN = 1.2 V, CIN = COUT = 0.47 μF, IOUT

= 1 mA.
