SS6117A

1A Low-Dropout Positive Regulator

FEATURES

DESCRIPTION

Dropout voltage 1.3V at 1A output current.

The SS6117A is a low-dropout three-terminal

regulator with 1A output current capability. The

output voltage is adjustable with the use of a

resistor divider or fixed at 1.8V, 2.5V, 2.85V, 3.3V,

or 5V. Dropout voltage is guaranteed to be a

maximum of 1.5V at the maximum output

current. The low dropout voltage and fast transient

response make this device ideal for low voltage

microprocessor applications. The current-limiting

and thermal protection reduce the risk of an

overload condition creating excessive junction

temperatures.

Fast transient response.

Line regulation typically at 0.015%.

Load regulation typically at 0.1%.

Current-limiting and thermal protection.

Adjustable output voltage or fixed at 1.8V, 2.5V,

2.85V, 3.3V, 5V.

Standard 3-pin power packages.

APPLICATIONS

Post Regulator for Switching Supplies.

Active SCSI Termination.

Battery Chargers.

Constant-Current Regulators.

Motherboard Clock Supplies.

TYPICAL APPLICATION CIRCUIT

V_REF=V_OUT- V_ADJ=1.25V (typ.)

V_OUT=V_REFx (1+RF2/RF1)+ I_ADJx RF2
