LM2937 500 mA Low Dropout Regulator

Check for Samples: LM2937

FEATURES

DESCRIPTION

The LM2937 is a positive voltage regulator capable of

supplying up to 500 mA of load current. The use of a

PNP power transistor provides a low dropout voltage

characteristic. With a load current of 500 mA the

minimum input to output voltage differential required

for the output to remain in regulation is typically 0.5V

(1V ensured maximum over the full operating

temperature range). Special circuitry has been

incorporated to minimize the quiescent current to

typically only 10 mA with a full 500 mA load current

when the input to output voltage differential is greater

than 3V.

•

Fully Specified for Operation Over −40°C to

+125°C

•

Output Current in Excess of 500 mA

Output Trimmed for 5% Tolerance Under all

Operating Conditions

•

Typical Dropout Voltage of 0.5V at Full Rated

•

Wide Output Capacitor ESR Range, up to 3Ω

Internal Short Circuit and Thermal Overload

Protection

•

Reverse Battery Protection

The LM2937 requires an output bypass capacitor for

stability. As with most low dropout regulators, the

ESR of this capacitor remains a critical design

parameter, but the LM2937 includes special

requirements. The LM2937 is stable for all ESR

below 3Ω. This allows the use of low ESR chip

capacitors.

Ideally suited for automotive applications, the LM2937

will protect itself and any load circuitry from reverse

battery connections, two-battery jumps and up to

+60V/−50V load dump transients. Familiar regulator

features such as short circuit and thermal shutdown

protection are also built in.
