Description
The Enable Input. An active HIGH input, turning ON the LDO. This input
should be tied to V IN if the LDO is not intended to be shut off during normal
operation. A pull ? down 2.5 M W resistor maintains the circuit in the OFF
state if the pin is left open.
Power Supply Ground; Device Substrate. The center pad is internally con-
nected to Ground and as such can cause short circuits to signal traces run-
ning beneath the IC. This pad is intended for heat sinking the IC to the PCB
and is typically connected to the PCB ground plane.
Bypass input. Placing a capacitor of 100 pF to 470 pF between BYP and
ground reduces noise on V OUT. This capacitor is optional and it increases
the turn ? on time.
Regulated Output Voltage. A protection block eliminates any current flow
from output to input if V OUT > V IN .
Output Voltage Adjust Input. This input ties to the common point of a resistor
divider which determines the regulator ’s output voltage. See Applications
section for details on selecting resistor values.
Positive Power Supply Input. Supplies power for V OUT as well as the regu-
lator’s internal circuitry.
