The LM2937ES-12/NOPB is a 12V low dropout 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. 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 LM2937 requires an output bypass capacitor for stability. As with most low dropout regulator, the ESR of this capacitor remains a critical design parameter, but this regulator includes special compensation circuitry that relaxes ESR requirements. The device is stable for all ESR below 3R. This allows the use of low ESR chip capacitors.
Stable power is ideal for better processing this LDO LM2937ESX-12/NOPB linear regulator developed by Texas Instruments will help do so. Its typical dropout voltage at current is 0.11@50mA|0.5@500mA V. It has an overall accuracy of ±5 %. This voltage regulation device"s single output can produce a current up to 0.5 A. With a voltage no larger than 26 V, this will supply sufficient power to your circuit. With a fixed output that has a voltage of 12 V, this is power management at its best. Using a load regulation of 12mV(Typ) and line regulation of 36mV(Typ) is needed for a programmable DC power supply. This product will be shipped in tape and reel packaging for quick mounting and safe delivery. The maximum dropout voltage is 0.25@50mA|1@500mA V. Its polarity is positive. This voltage regulation device has a minimum operating temperature of -40 °C and a maximum of 125 °C.
Use the single MIC5237-5.0YU linear regulator from Microchip Technology to maintain a constant output voltage. This device has a maximum power dissipation of No mW. It has an overall accuracy of 1250 %. This voltage regulation device can produce a current up to 0.4 to 1 A. It only needs a voltage of at least 4 V while not exceeding 6% V to effectively power your circuit. With a 62 output that has a voltage of >=100 V, this is power management at its best. Its maximum power dissipation is No mW. This voltage regulation device has an operating temperature range of -65 °C to 150 °C. Its polarity is 0.5.
