Texas Instruments LM2937ES-3.3/NOPB LM2937ES-3.3/NOPB Fixed LDO Voltage Regulator 4.75V to 26V 500mV Dropout 3.3Vout 500mAout TO-263-3

The LM2937ES-3.3/NOPB is a Voltage Regulator capable of supplying up to 500mA of load current and is ideal for converting a common 5V logic supply or higher input supply voltage, to the lower 3.3V supplies to power very-large-scale integrations (VLSI) ASICs and microcontrollers. 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 5V. The LM2937 requires an output bypass capacitor for stability. As with most regulators utilizing a PNP pass transistor, the ESR of this capacitor remains a critical design parameter, but this regulator include special compensation circuitry that relaxes ESR requirements and is stable for all ESR ratings less than 5R. This allows the use of low ESR chip capacitors and features short circuit and thermal shutdown protection are also built in.

• Output trimmed for 5% tolerance under all operating conditions
• 0.01 to 5R Wide output capacitor ESR range
• Internal short-circuit and thermal overload protection
• Reverse battery input protection
• 60V Input transient protection
