1 Features 3 Description
The LM2937 is a positive voltage regulator capable of
1• Fully Specified for Operation Over −40°C to 125°C
supplying up to 500 mA of load current. The use of a
• Output Current in Excess of 500 mA PNP power transistor provides a low dropout voltage
• Output Trimmed for 5% Tolerance Under all characteristic. With a load current of 500 mA the
Operating Conditions minimum input to output voltage differential required
• Typical Dropout Voltage of 0.5 V at Full Rated for the output to remain in regulation is typically 0.5 V
(1-V ensured maximum over the full operating Load Current
temperature range). Special circuitry has been
• Wide Output Capacitor ESR Range, up to 3 Ω incorporated to minimize the quiescent current to
• Internal Short Circuit and Thermal Overload typically only 10 mA with a full 500-mA load current
Protection when the input to output voltage differential is greater
than 3 V. • Reverse Battery Protection
• 60-V Input Transient Protection The LM2937 requires an output bypass capacitor for
stability. As with most low dropout regulators, the • Mirror Image Insertion Protection
ESR of this capacitor remains a critical design
parameter, but the LM2937 includes special 2 Applications compensation circuitry that relaxes ESR
• Automotive requirements. The device is stable for all ESR below
3 Ω. This allows the use of low ESR chip capacitors. • Industrial Control
• Point-of-Load regulation
