LT1175

500mA Negative

Low Dropout Micropower

Regulator

FEATURES

DESCRIPTION

The LT^®1175 is a negative micropower low dropout

regulator. It features 45μA quiescent current, dropping

to 10μA in shutdown. A new reference ampliﬁer topology

gives precision DC characteristics along with the ability to

maintain good loop stability with an extremely wide range

of output capacitors. Very low dropout voltage and high

efﬁciency are obtained with a unique power transistor

anti-saturation design. Adjustable and ﬁxed 5V versions

are available.

Operating Current: 45μA

Adjustable Current Limit

Low Voltage Linear Dropout Characteristics

Stable with Wide Range of Output Capacitors

Shutdown Current: 10μA

Positive or Negative Shutdown Logic

Fixed 5V and Adjustable Versions

Tolerates Reverse Output Voltage

Available in 8-pin PDIP and SO Packages, 3-lead

SOT-223, 5-Pin Surface Mount DD and Through-Hole

TO-220 Packages

Several new features make the LT1175 very user-friendly.

The SHDN pin can interface directly to either positive or

negative logic levels. Current limit is user-selectable at

200mA, 400mA, 600mA and 800mA. The output can be

forced to reverse voltage without damage or latchup. Un-

likesomeearlierdesigns,theincreaseinquiescentcurrent

during a dropout condition is actively limited.

APPLICATIONS

Analog Systems

Modems

Instrumentation

A/D and D/A Converters

The LT1175 has complete blowout protection with current

limiting, power limiting and thermal shutdown. Special

attention was given to the problem of high temperature

operation with micropower operating currents, preventing

output voltage rise under no-load conditions. The LT1175

is available in 8-pin PDIP and SO packages, 3-lead SOT-

223 as well as 5-pin surface mount DD and through-hole

TO-220 packages. The 8-pin SO package is specially

constructed for low thermal resistance.
