LT3088

800mA Single Resistor

Rugged Linear Regulator

FEATURES

DESCRIPTION

The LT^®3088 is an 800mA low dropout linear regulator

designed for rugged industrial applications. A key feature

of the IC is the extended safe operating area (SOA). The

LT3088 can be paralleled for higher output current or heat

spreading.Thedevicewithstandsreverseinputandreverse

output-to-input voltages without reverse current flow.

Extended Safe Operating Area

Maximum Output Current: 800mA

Stable with or without Input/Output Capacitors

Wide Input Voltage Range: 1.2V to 36V

Single Resistor Sets Output Voltage

Output Adjustable to 0V

50µA SET Pin Current: 1% Initial Accuracy

The LT3088’s precision 50µA reference current source

allows a single resistor to program output voltage to

any level between zero and 34.5V. The current reference

architecture makes load regulation independent of output

voltage. The LT3088 is stable with or without input and

output capacitors.

Output Voltage Noise: 27µV

RMS

Parallel Multiple Devices for Higher Current, Heat

Spreading and Lower Noise

Pin Compatible Upgrade to LT1117

Reverse-Battery and Reverse-Current Protection

<1mV Typical Load Regulation Independent of V

<0.001%/V Typical Line Regulation

OUT

Internal protection circuitry includes reverse-battery and

reverse-current protection, current limiting and thermal

limiting. The LT3088 is offered in the 3-lead SOT-223,

3-lead DD-Pak, and an 8-lead 3mm × 3mm DFN package.
