LM2937
500mA LOW DROPOUT
VOLTAGE REGULATOR
DESCRIPTION
LINEAR INTEGRATED CIRCUIT
The UTC
LM2937
is a positive voltage regulator capable of supplying
up to 500mA of load current. The use of a PNP power transistor
provides a low dropout voltage characteristic. With a load current of
500mA the minimum input to output voltage differential required for the
output to remain in regulation is typically 0.5V(1V guaranteed maximum
over the full operating temperature range). Special circuitry has been
incorporated to minimize the quiescent current to typically only 10mA
with a full 500mA load current when the input to output voltage
differential is greater than 3V.
The UTC
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
compensation circuitry that relaxes ESR requirements. The UTC
LM2937
is stable for all ESR below 3Ω.This allows the use of low ESR
chip capacitors.
Ideally suited for automotive applications, the UTC
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.
FEATURES
* Fully specified for operation over -40C~ +125C
* Output current in excess of 500mA
* Output trimmed for 5% tolerance under all operating conditions
* Typical dropout voltage of 0.5V at full rated load current
* Wide output capacitor ESR range, up to 3Ω
* Reverse battery protection
* Internal short circuit and thermal overload protection
* 60V input transient protection
* Mirror image insertion protection
* Built-in ON/OFF control function
