LM2991QML Negative Low Dropout Adjustable Regulator

Check for Samples: LM2991QML

FEATURES

DESCRIPTION

The LM2991 is a low dropout adjustable negative

regulator with a output voltage range between −2V to

−25V. The LM2991 provides up to 1A of load current

and features a On /Off pin for remote shutdown

capability.

•

Output Voltage Adjustable From −2V to −25V

Output Current in Excess of 1A

Dropout Voltage Typically 0.6V at 1A Load

Low Quiescent Current

Internal Short Circuit Current Limit

Internal Thermal Shutdown with Hysteresis

TTL, CMOS Compatible ON/OFF Switch

Functional Complement to the LM2941 Series

The LM2991 uses new circuit design techniques to

provide a low dropout voltage, low quiescent current

and low temperature coefficient precision reference.

The dropout voltage at 1A load current is typically

0.6V and a ensured worst-case maximum of 1V over

the entire operating temperature range. The

quiescent current is typically 1 mA with a 1A load

current and an input-output voltage differential greater

than 3V. A unique circuit design of the internal bias

supply limits the quiescent current to only 9 mA

(typical) when the regulator is in the dropout mode

(V_O− V_I≤ 3V).

APPLICATIONS

•

Post Switcher Regulator

Local, On-card, Regulation

Battery Operated Equipment

The LM2991 is short-circuit proof, and thermal

shutdown includes hysteresis to enhance the

reliability of the device when inadvertently overloaded

for extended periods.
