Typical Applications

Low T.C. Current Sink

DS011962-32

5V Bus Current Limiter with Load Fault Indicator

DS011962-33

*Output voltage equals +VIN minus dropout voltage, which varies with

output current. Current limits at a maximum of 1000 mA (typical).

**Select R1 so that the comparator input voltage is 1.23V at the output

voltage which corresponds to the desired fault current value.

5V Regulator with Error Flags for Low

BATTERY and OUT OF REGULATION

DS011962-34

*Connect to Logic or µP control inputs.

LOW BATT flag warns the user that the battery has discharged down to

about 5.8V, giving the user time to recharge the battery or power-down

some hardware with high power requirements. The output is still in

regulation at this time.

OUT OF REGULATION flag indicates when the battery is almost

completely discharged, and can be used to initiate a power-down

sequence.

5V Regulator with Snap-ON/Snap-OFF

Feature and Hysteresis

DS011962-35

*Turns ON at VIN = 5.87V

Turns OFF at VIN = 5.64V
